Help me find this BL

So the MC is this guy who had to dress as a girl in order to comfort an old dying man. MC gets paid for doing this, the money being the reason MC does it in the first place. ML is like the grandson of the old man. ML starts out hating MC because he knows MC is just using his grandfather however ML slowly starts to fall in love with the crossdressed MC. Eventually the MC has to leave tho and gets separated from the ML. Years pass by and the MC and ML meet again however ML got amnesia and forgot all about MC. ML only remember MC as vaguely resembling the girl from when he was younger that took care of his grandfather. Slowly ML starts to fall in love with MC again as they spend more time together. I remember at some point a girl is the first one to recognize MC and ML takes MC to his grandfather’s house to help him pack up all of the stuff there. I remember really liking this BL but I can’t for the life of me remember the name.
