@cookie_honey but the drawing didn't show a tight hug, and yes Asian like Chinese, Japanese, Korean, Vietnamese (especially before modern time, ancient time like this manhua) mostly have a small breast while a plump ample bosom are rare; in modern time a small breast to the point [doesn't need bra but miniset is sufficient] is rare while usually A cup is more common, B cup is common, I don't know about C cup but I never seen relatives using C cup (even if artist or celebs have, usually we believe it's through surgery because above B cup is pretty rare compare to their skinny/normal body. Of course there's possibility it's natural but who cares about that unless they're fanw, anti fans, or something)
Edited: although using A or B cup, the cup has a pretty stuffy sponge to make them bigger and have good shape but there's also a lot of people that prefer not so stuffy sponge or without sponge
My information is limited to my knowledge, so I might be wrong but hopefully it can help even a bit
Lol, Ikr, he's so desperate to be with MC (beside MC already promised to never step again near them much ML so their meeting is heaven blessing in ML's pov)
