im looking for this one romance manga, where the ml is a yakuza (?) and the fl is a lady who wants to find a bf. i don't remember much about it but theres this one part where the fl got locked into some kinda basement cuz theres like shootings going on. the guards who works under the ml didn't let her out cuz they don't want her to get hurt. pls help me find this (´°ω°｀)

i saw this one manga, not sure if its shoujo or not but the title goes like "he has a pretty face and he hides it" pls help me find this T_T
