I would gaf but it's this exact behavior that made MC lie in the 1st place
But they are not partners. ML made it clear he isn't interested in love, they never agreed to be boyfriends, but he still wants to be the only one the MC spends his time with. He is possessive and manipulative, but the MC never catches on to that. He knows that meeting up with his friend will upset ML, and still he does not see all the red flags
What manhwa are you even talking about cause the fact that they aren't partners got mentioned like over 10 times already lmfao. Why don't you actually read it instead of talking out of your ass? The MC gets scared of the ML just thinking of the imaginary things he could've done, he was bound to lie.









The MC is a mature adult, of course he's literally a teacher. But that's probably not the only reason he confessed. They also happen to be in the middle of an Apocalypse so...
