The morning after Chizuru’s birthday Kazuya checks under the wall separating their balconies to confirm she took the gift. The neighbors exchange good mornings, and while Kazuya is stressed about how she felt about the gift, she comes right out and says the plums were good. She’ll also believe him when he says nothing happened with Ruka.
He wants to rent her Wednesday night, but her college friends are taking her out for drinks. Kazuya’s mates (who always wear thin) happen to drag him along for drinks as well. Kazuya didn’t know they’d be meeting girls and Chizuru didn’t know they’d be meeting guys, so naturally the two end up at the same bar together by pure coincidence (or purified luck).
An increasingly rowdy college bacchanalian ensues, with both Chizuru’s and Kazuya’s friends going with the good vibes and getting right trashed, all while Chizuru sips her tasteful newbie drinks with a calm dignity. Alas, when her friends get sufficiently boiled they’re not above fondling her boobs or snatching her glasses.
It’s here where anime magic must hold sway, because tipsy or not these people would surely know Mizuhara Chizuru and Ichinose Chizuru are one and the same. That said, those bamboo shoot rounds are brutal. Not wanting Chizuru to get sick on her first night of legal drinking, he loses on purpose again and again.
The end result is that he leaves the bar with an acute case of the bad spins. If Chizuru despised him she’d just leave him to the night, but he’s a neighbor, and while she’d like to deny it, he’s more than just an acquaintance or client too. So she helps him home and unlocks his door so he can go inside and pass out.
Even then, she’s not about to leave him alone in this state, especially since she knows all too well he lost the drinking game on purpose. While praying to the porcelain god he mutters something about always causing trouble for Mizuhara, so he at least wanted to look out for Ichinose.
This moves Chizuru to the point she rubs his back to help him vomit more efficiently. And while Kazuya is a bad role model for basically binge drinking, he did it with noble intentions., and seeing the two of them in such a messy, human, vulnerable, relatable domestic scene, was very wholesome and satisfying. They really have each other’s backs.
