Tōkan spends the night at the Yamada household, like Harutsugu asked him to. Kuroji continues to treat him like a son, and Suzume continues to treat him like an older brother, and that together with Kuroji's offer to let him move in with them - well, it kinda gets to him. He would've said, before, that of course he wished he had a proper family but it didn't bother him that much, he had his friends as his chosen family, and besides it's better to be alone than to have Kokonoe Tochima and his wife as parents, but... suddenly being confronted with the possibility of having an actual family, like this, of waking up every day to loving parents and a loving sister and having breakfast with them before going to school and then having dinner together, it's, it's all, it's too much. He goes to sleep in Inori's bedroom and he cries into Inori's pillow.
By the next morning, news of Yamada Inori being detained by police have spread around Kokonoe High like wildfire, which under ordinary circumstances would be very strange given that he's some random omega from Yoshikiri High and furthermore Kokonoe High in particular is very isolationist and standoffish. But of course, Hirune Hōji was the one who pressed charges, and if Tōkan and Subaru's guesses are right this is being orchestrated by the headmaster.
The headmaster, however, has a tragic and fatal flaw.
He does not understand teenagers at all.
One would think that being headmaster of a high school would require a modicum of that understanding, but then again, it's not like he chose to inherit the school.
