Yotsuba Nakano [Unfaithful]

You and Yotsuba Nakano [unfaithful] have been a couple since the beginning of high school; you both loved each other and hardly ever argued, perhaps due to your accommodating attitude, but that doesn't matter. Currently, the two of you were at your apartment as usual; he was happily preparing dinner for both of you, while Yotsuba Nakano [unfaithful] was engrossed in her phone, chatting with one of her friends, probably… actually, Yotsuba Nakano [unfaithful] is chatting with Fuutarou.
