While there are a couple of friendly voices among them (namely Ichika and Yotsuba), as a group the Nakano quints are adamantly opposed to being tutored by Fuutarou. When he challenges them to score at least a 50 in a test he provides, they manage to score 100…combined. They then physically run away from him, but they underestimate how bad he needs the money, not to mention not shirking from this challenge is a matter of personal pride.
Fuutarou knows the sisters hate studying—and him, Yotsuba and Ichika aside—but he’s determined to find a way to get to them, even if it’s one sister at a time. This week his focus is on the third sister Miku, the only one to score a certain question correctly. When he approaches her about it he’s interrupted by Yotsuba and then Ichika, the latter of which thinks they should be more focused on falling in love than studying.
Little does Ichika know that Miku has already fallen in love…with Sengoku period warlords. She slips what looks like a love letter in Fuutarou’s desk and meets him on the rooftop to confess that love, which he thought for a minute was love for him. She dismisses her encyclopedic knowledge of them to be something weird, but he encourages her to have faith in what she likes, finally seeing a path to get her excited about studying.
Miku initially agrees to let him tutor her, but when she offers him a can of her favorite matcha soda and mentions it doesn’t have snot in it, Fuutarou fails to identify the reference, and she recinds her offer to cooperate, labeling him as “all talk.” This irks him, so he checks every Sengoku book in the library, and the next day challenges her to a trivia game. Because it’s a subject near and dear to her heart, he knows she won’t back down.
However, she not only backs down, but runs away, forcing Fuutarou to chase after her as they play a game of warlord shiritori, until they both collapse from exhaustion. Miku removes her stockings and shoes and relaxes on a bench as Fuutarou gets her a matcha soda and tells her he figured out the snot reference—but only after Yotsuba googled it for him. Miku reiterates her lack of confidence in herself, telling him she’s the “biggest loser” of the group, and that her four sisters can do anything she can.
Fuutarou counters by showing her the sisters’ test answers, which show that no sisters got the same answers right. That means it goes both ways: Miku can do anything her sisters can, if she applies herself. Fuutarou can see light at the end of the tunnel; if each quintuplet has a specialty that will help make being tutored acceptable, than he can pool their collective knowledge to help them all succeed.
But while he seeks to be the grand uniter of the quintuplets, for now it’s just Yotsuba and Miku who have stopped running away from studying, and from him. Complicating matters is Yotsuba’s suspicion that Miku is in love with Fuutarou, which Miku neither confirms nor denies but blushes an awful lot when pressed. This proves to be a fascinating journey!
