So ML knew MC’s mom since he was like 10(?). He met her at an orphanage and she happened to sponsor him. She found a family to adopt him. His family loves him. They kept in contact throughout the years but their relationship wasn’t exactly affectionate (?). Anyways one day the mom contacted him and asked him to tutor MC because the mom is worried about him and having someone close in age would maybe help MC open up about his troubles. ML knew from the start about everything and he agreed cause well the mom is his benefactor? He expected MC to be a brat spoiled by the almighty mom but he met a quiet and shy MC and kinda quickly took a liking to him and started worrying about him and everything. He was pretty genuine about how he treated Wooyeon besides how their tutoring started and him getting updates from the mom, when Wooyeon got send home from school because he beat up the bully. He was always worried about him being alone and all that. He was also feeling really guilty the whole time and when Wooyeon confessed ML knew he needed to draw a line and then disappeared. he has been feeling guilty about it since!
