Is it a manga or manhwa?
manwha
Ummm.. I'm not sure, but are you talking about the dads from "love shuttle"?
nooo they were a side couple shown after the chapters with the main couple. Honestly I didn’t read the main couples story so idk the plot but I remember the uke and seme growing up together. The uke was shorter than the seme and then had a growth spurt and was a bit insecure abt it
I remember reading this comic where the side couple had a taller uke. I don’t remember the plot but i remember them being so cute. I think it was a college/after college setting
