hellooo, can you spoil me on the second part you meant, like apples in newton's theory
It's a crime to not give the details :p

Long story short, MC will soon get drunk again and talk with ML and confess about his feelings and get to know that ML has always known that he was his student, just never said anything. Then they will start to date, and halfway through it, the ML in the other manhwa (omega complex) will make a small apparition, leading Dohyun/ML talking to one of his friends about his old crush on MC in omega complex (forgot their names sorry). And then our MC will actually hear the conversation between Dohyun/ML and his friend and come to know about the old story that happened between them. But as far as i remember it won't really affect their relationship nor will it add more angst to the plot, since MC was pretty nonchalant about it.
Anyway those are the key points that i mostly remember, but my mind is a bit fuzzy about it so I'm not sure if all is fully correct but that's pretty much it.
I can't wait for the dating, the falling out, and the comeback to happen. Their chemistry is just SO good.
