I'm here to bring the news that I found a volume 3 and that there's a new character that I think would take interest in Tsugumi (I don't know if it's in a good or bad way bc the one I read was in Korean and I only understand a few sentences, maybe it'll help if the one I found was in Spanish because there were some Spanish words scattered in some chapters)

This is the only sharper I found.
I'm sure you'll finish your science project with this one~~ hehehe

I saw the Hiroto-Kakeru thing happening but not them becoming brothers. I was so confused when it narrated that the small guy was Hiroto and Kakeru's lil bro
»I also want to talk about kids in yaoi manga (or any manga). They're like what makes the manga better for me, especially if the art style is cute and if the kids act cute too
Wait I just realized I read this but I haven't read the sequel(?) to Sohta and Tsuji's book so I was like "tf are these two doing in here?"
