It's clear he hasn't liked her since school days and probably hasn't even realised that his feelings already crossed…
Just like the drama "As Beautiful As You", ML from having a relationship and a fling to a 30 years old virgin, who know what the writer will do, love triangle, ex comeback 🗿, hopefully not.
That it!! Damn, the satisfying revenge would be his mom and dad got divorce and loss all of their asset because of that stupid ceo, 2ML became disabled, FL involved in malpractice and got into jail. While ML left Korea and start his healing journey with 2FL.
While FL has been in a relationship for 7 years, she can't handle it maturely, whereas ML, a virgin since birth, handles his relationships professionally.
