last time i didn't get anything so here i go again

So their was this MANHUA I read 1 or 2 years ago could anyone help me find it

Mc:pink hair
Ml:black hair

So the mc had liked the ml for quite a while and they started dating but the ml is pretty much emotionless(thats just his personality tho)and the relationship is pretty one sided with the mc doing all the work and effort although his mom(who is rich) is telling him he should find someone who reciprocates his feelings but the mc is stubborn.

And at some point later on in the story the ml get a chance at a major promotion and gets to work overseas but the mc who at this point in the relationship is pretty tired and worn out by catering everything to the ml so he does no leave him(btw the ml does not know the mc I catering to his needs and thinks he is in a perfect relationship with the perfect partner and both of them are happy in other words he’s ignorant) and this is the final straw.

The mc basically begs on his knees for the ml not to leave but the ml who only thinks about things logically is saying that the mc is being irrational and that they can just have a long distance relationship so the ml leaves overseas thinking that the mc is just pouting/throwing a tantrum and will contact him again but the mc never does.

So now theirs a time skip and the ml comes back to Korea for work and the person he is negotiating with turns out to be the mc. The ml desperate to get the mc back and try’s to win him over but the mc gets annoyed and says he is strictly here for business and if the ml keeps on blabbering nonsense he will leave(but its not really the groveling type because the ml of the past had been pretty emotional unaware but the ml now has realised his ignorance and become emotionally aware thats the main difference. What im trying to say is that the ml is not really bad he just need to be guided).

And so that’s were I left of and I am desperate to find this story again so if anyone might know its name or the link pls tell me ╥﹏╥
