Watari-kun's ****** Is About to Collapse Vol. 10 (Kodansha, 2021)

After breaking up with Ishihara-san, Naoto ended up alone together with his childhood friend Satsuki, and almost took her up on her offer to comfort him. Since Naoto wouldn't have sex with her unless they are going out with each other, Satsuki told him to ask her out by the day of the school festival. On the other hand, Ishihara-san, believing that the festival's curse will bind them together forever, is planning to get back together with Naoto. Meanwhile, Naoto is plagued with uncertainty. Who will he ultimately choose on the day of the festival?!
