Yesterday i found good bl manhwa on b*t*t (idk if the manhwa in this website/not yet) but i felt asleep and my chrome restarted aughh i really appreciate it if someone know this and tell me the title. Here's the manhwa summary :
Mc's friend give mc a novel about omega that get sold to his highschool friend (ML). This ML really hate the omega cuz out of nowhere the omega left him on highschool when he was at his lowest time of life and the ML felt betrayed (cmiiw). Despite all of that, the ML still love him in the future (although it was twisted) . Then this manhwa story tells the story about the mc got isekai-ed to this novel but strangely his face and the ML of the novel face resemble him and his friend who give the mc da novel. Because the ML had his friend face, MC cant help but keep laughing whenever the story get serious.
I still remember some of the plot but it definitely will be a spoiler so i just stopped here. If some of you know what this manhwa is you really made my day!!!

Does anyone know the name of the new BL anime with an isekai theme? I feel like I've seen its animation somewhere. Is it just promotion, or am I just imagining things? Please help me
