Humm

No they're both adults since college in kr is uni. They're both in their twenties but you might not like their first encounter/past life. Seme saved uke as a child and encounters/nurtures uke throughout adolescence, which then leads to a romantic relationship when he grew up in past life. That's how things are looking, I'm not a big fan of that part myself. But in current life, both meet so far and have fucked as adults

Thank you for responding. I took a look at the pictures and it looked like a child... (⊙…⊙ )

its just size difference yaoi, MC doesnt look like an underage boy.. hes just a bit more petite/scrawny but still reads and is drawn as adult ML is just MASSIVE in size and muscles
