I forgot the title of this chinese BL where the uke has a system who goes to different world and he keeps dying - that's his mission
And the seme kept falling in love with him
Idk why but the only manhua that came up to my mind is "I have to be a great villian" maybe this is not the one
manhwa where uke hide from the seme in the secret room inside seme's house. he could still see the seme through cctv and he lets out pheromones when he sees the seme got hurt. this is the redemption arc
