spoiler !!!
hii since i have read the novel then this is what gonna happen next
shirayuki wont do anything to his brother (surprise and expected to me ) but told him to meet up with haruki with him the next day. When they meet again haruki pretended to not know nanami the other day and haruki want them to becomes friends 🤭🤭. Nanami has some kind of "curious feeling" for haruki after that.
