While cleaning the pool Mikasa seems overly friendly and casual with Fuuka, which increasingly annoys Yuu. He wants Fuuka to hit him for being superficial, but Fuuka is casual in return. Yuu can't understand why Fuuka is so easygoing with Mikasa, but angry and violent towards him. Coming to the conclusion that maybe they like each other, he tries to mind his own business.
Fuuka notices that Yuu isn't sweeping properly and goes over to help him. She promptly slips and falls on the floor, soaking her clothes. Yuu catches a glimpse of her panties Through her wet skirt before turning away in embarrassment. Mikasa notices and Fuuka storms off to change.Mikasa notices a sour look on Yuu's face and Yuu stammers that he and Fuuka seems to be really close, to which Mikasa agrees. Mikasa tells Yuu that he should socialize more instead of messing around with his phone. He invites Yuu to have tea with he and Fuuka after cleaning. Yuu begins to resent Mikasa because of his kindness towards him despite being popular. He makes Yuu feel that a pitiful person like himself is undeserving of such attention.
Yuu declines, saying he does not want to be in he and Fuuka's way, since they seem to like each other. Mikasa tells Yuu he's gay. Then he tells Yuu that he's comfortable telling people because he doesn't want to lie in order make others accept him. Yuu is moved by this because he always lies on Twitter to make himself look good. He tells Mikasa that he thinks he's cool for living honestly, and Mikasa says that Yuu is a friendlier person than he appears to be, and maybe that's why Fuuka is drawn to him.
While pondering what Mikasa just said to him, Fuuka returns and asks what the pair are talking about. Mikasa jokes that Yuu said he was glad to see Fuuka's panties, and she slaps Yuu.
Later that evening, Yuu texts Tama about his day and how he has made two new weird friends.
