Plot
Nagatoro ask Senpai if he wanted to see some “hot snaps” describing them as "cool" and "all natural", prompting the boy to imagine it were naked pictures of her, however Nagatoro quickly revealed she intended Snapping Hot Chicken accusing him to be a pervert because of his thoughts.

Later, Nagatoro and her friends watch from their classroom window as the second year students were having a marathon, immediately spotting Senpai and marveling at how poorly he was performing, since he was way behind everyone else. After classes, Nagatoro went to Senpai and playfully told him that, as his kōhai, she was embarrassed for him, however when he replied that "all he can do was draw" she was greatly bothered, getting so motivated and angered by his lack of self confidence to begin personally train him. The following day, despite being a weekend, Nagatoro forced Senpai to join her in the marathon training, showing up with her hair in a ponytail as well as wearing a skin-tight skimpy top and short, turning on the introverted boy who couldn't help but to stare at her sweaty and barely covered behind while running their 5Km route. This caused Senpai to up his pace in order to stay in front of Nagatoro and don't risk be accused of perverted thoughts. After covering half of the route, Senpai collapsed and asked Nagatoro to stop, causing her to insult him to provoke him, going as far as to slap her own butt telling him to try to catch her if he was angry. Senpai reprised the run angrily, causing the girl to smile and sweetly told him to do his best.

Eventually Senpai managed to run all the way the 5 km route of the marathon training and Nagatoro told him to do some stretching; however as they stretch she noticed how stiff was Senpai's body, suggesting him to do a forward bent and showing him how to do it, thus causing him to vividly blush as he was having trouble the entire day not to gawking at Nagatoro's butt. Since Senpai's body began to shake, Nagatoro start to help him doing the exercises in pair until his body get more and more flexible. However while they were doing their last stretching position, Yoshi passed by while walking her dog and, seeing them, asked if they were trying the fusion from , embarrassing them both.

Sometime later, with the Culture Festival getting closer, Senpai has trouble in finding someone to model for him. Overhearing as he was having said thoughts out loud, Nagatoro made Senpai explain everything to her with the intention of being asked to help him, however the boy refuses to use her as a model since he considered too hard to draw the female figure. Due to the girl insistence, Senpai eventually decided to tell her he would have used her as a model only if she posed cosplaying in her infamous Nekotoro version, sure that the girl would be unable to find said costume or in any case too embarrassed to wear it. The following week, much to Senpai's surprise, an utterly ashamed Nagatoro shown herself into the art club room wearing a perfect Nekotoro costume that she asked the handicrafts club to made her. The girl insisted that he say something and get really mad when he simply complimented how the outfit was well made.

Meanwhile, Gamo-chan, Yoshi and Sakura peered into the room; then they joined them as Nagatoro posed for Senpai's painting, teasing him to making her look sexy or mocking him for his embarrassment. Later, the girls started to chat regarding what they planned to do with their clubs or class for the Cultural Festival, then, while asking what would be the art club exhibition Senpai stared into space and began to remember: The previous year, while still a freshman in high school, he helped the zealous President of the club to organize the art display for previous Cultural Festival's exhibition, which is revealed to be a huge success; the boy indulged in how much he admired the driven, charismatic and amazing person the she was and how the last day of their exhibition she thanked him for having allowed her to have some good memories before having to go to cram school like all the second years, thus becoming unable to join club activities anymore and leaving the art club to him. After Nagatoro woke him up from his memories, Senpai answered that he would probably make an art display like the previous year, causing the girls to said it would be boring and that they would give him an hand to fire it up a little. Nagatoro ironically suggested it would be fun to have games in which torturing him or a kitty-themed while Sakura suggested a cross-dressing café featuring Senpai dressed like a female maid, which a secretly amused Nagatoro refused, fearing the boy could get too much attentions. In that exact moment, Senpai heard some familiar footsteps and asked the girls to hid in the prep room right before the President entered with a stern expression.

The President told Senpai that she would help the art club display by submitting also one of her painting, then she scolded him for some rumors she heard about the club room having become a hangout for a bunch good-for-nothing. In the meantime, while eavesdropping on their conversation hidden in the prep room, Sakura, Yoshi and especially Gamo-chan all teased Nagatoro saying that beautiful older girl is probably Senpai's ex. While the President told Senpai she was disappointed for him inviting people and being rowdy, reminding him that the art club was not a playground, the still-hidden girls felt kind of sorry and apologized, although only internally. The President, also saw Senpai's paint of Nekotoro and criticized it, saying that wasn't the manga research club, then informing him that she spoke with the student council and was thinking about disbanding the club. Due to Senpai being unable to reply, Nagatoro came out of the prep room with her friends and face the President herself accusing her of being selfish and unreasonable as she was the one who abandoned the club only to suddenly walk back in it talking about disbandment. The President dismissed said accuse stating that if the only club member lacked motivation there were no reason for the club to continue, thus angering Nagatoro who finally lashed out making her feelings for Senpai transpiring and yelling that even by himself he has always worked really damn hard. Hearing this, the President suggested that Senpai held his own art display independently from the club and, if he defeated her display in the school's popularity contest she would have rescinded the club's disbandment. Although Senpai was not very confident about it, Nagatoro immediately accepted the challenge in his stead.
