The loan shark went to find him in his home and trashed everything inside , they hurt him and he was almost gangrape then Jaekyung came to his rescue. I mean came to Doc Dan's house and just coincidentally right on time he saw the act, he fought with them and save doc dan. After that he paid off doc Dan's debt and let him stay his house and paid the hospital bill for his grandma.The reason Why I like Jaekyung even though he do some lil shameful or bad things to doc dan (sex or trashed doc Dan's gift, got angry after the incident). Anyway it's a misunderstanding and we must admit there's negligence of doc dan, the part where he mistakenly sprayed the chemicals, and he also did not tell Jaekyung right away about him meeting with the sparing enemy coach, so I can't fully blame why Jaekyung got mad after that. I'm not so close minded to hate ML right away I always balancing the situation.
Because I read a lot of red flag ML and what Jaekyung did to doc dan was just a lil portion of the good thing he did for him and they both benefited for it. Doc dan likes him let say feel in love with him in the process while Jaekyung still in denying stage yet he felt jealous when the actor flirted with him.
I know lot of haters would disagree with me hello! But if it happens to me I will still grateful for him saving my life and my grandma's life. After meeting him ,bthe hospital give his grandma a good medical attention.
2nd time doc Dan's savior ! The great Jaekyung!
