From the manga magazine Dessert which came out 8/24
No recap, just a preview.
I think Rika might actually be in love with Sekai. I thought about it before but with this chapter I think it’s even more likely. Her reaction at the end is pretty telling. She rejected him before because he wasn’t serious and she didn’t want that and she got close to Rinri because Sekai took an interest in her.
…Or not ah ah. We’ll see. All this might just be a red herring. I’m also not quite sure what’s going on with Sensei. A part of me even thought he was actually already dating Rika lol (whatch that turns out to be the case^^).
