Both are currently airing shows with one of the main leads involved with the mafia. They are both crime/thrillers and have similar vibes.
Its a Chinese BL where the leads are in the same age bracket as the ones in Ash. Kingston(Foon) and Ollie(Zhen Xin) were also in Chinese survival shows for debuting idol groups so they have a lot of fans in common who would want to watch the shows they are in. Also most people interested in a BL from Hong Kong are also fans of chinese BLs and Deep In is of a similar genre so they'll enjoy watching it if they enjoyed Ash.
