It's a korean BL manhwa. The plot is about Jooha, a prostitute and a restaurant worker(who can shoot pearls out of his d-ck during an orgasm) who meets Dooshik, a jobless but sexy guy. Trust me, their story is so beautiful. Beware of carrying tissues with you while reading it.
A : Why are you crying?
B : It's tears of happiness. I just finished Pearl Boy.
