I love mafia bosses haha, idk but in BL stories I've seen many mafia guys who're a bunch of dangerous cuties, or hardcore dangerous guys but with a soft and precious spot for their lovers and idk, that for me is quite an original mixture that I love a lot! I guess it just depends on how hardcore it'll be the story and the main couple's chemistry, but here it seems it'd be something quite chill and cute lolol so I'm ok with that (but yeah, highkey I was expecting a 2nd gen. chaebol or someone rich boss -not that type of boss tho, lmao-).
I totally think the BFF like our MC, all his girlfriends look the same and almost identical to him so that's for me a signal. Anyway, I still don't care much about him tbh. I loved how Sangwha didn't care about him either and got super excited about the Hyung instead. XD
