Same I think that his dad is going to beat him really bad as In chapter 98 he said how how shinjin and joy were still hanging out together and he doesn't listen to him. And I'm pretty sure he also says how he has to teach him a lesson. I'm just so worried that he's going to get badly hurt and left to die.
i really want him to have a happy ending but his dad seems like the one to cover up a murder like saying he’s homeschooled and he’ll say he’s got bullied and beaten by classmates to blame on the bruising then say the boy killer himself and because no one talks to him only joy and the girl can defend him but the dad holds more power it’s sad really

kinda spoiler.. after he faints joy takes him to the nurse and that teacher that always snitches tells the dad they’re hanging out with eachother and then the dad is like fuming that’s what i’ve read so far but in my opinion it seems like the dad will beat him to a near death state and joy will realise he’s not turning up to school and go to the house when the dad leaves finding shinjin unable too move because of pain and malnourishment and near enough dead and joy parents come back and take him in or he moves in with joy sounds bad but i want a happy ending and the dad to suffer greatly
