ok this is my first time asking a question here so I might be bad at explaining(sorry( ̄∇ ̄"))
so it's a BL where the MC has a really good sense of smell, he had it since he was young. (i remember this scene where his mom or uncle picks him up from school and he guesses the food and they're all surprised) And so this one time he gets kissed when he's asleep and all he remembers is this lemon sent.
it's a BL manhua/manhwa where the mc(boy) talks to someone online and he tells him that he wants to kill someone and the person he's talking to says that he also has someone he wants to be killed. They decide that OP(online person) will kill the person mc wants killed and mc will kill for OP
Spoilers(i think):
later OP stalks mc. A scene i remember is when it was mc's birthday he gave him fireworks
that's all, thanks
