He did it out if pity the first time he rescued him and took him to the hospital. It's different this time. He felt anger and frustration over Yeomin situation. He even asked his secretary to investigate the matter. He's doing it out of affection but he didn't realize it yet
Finally, its going in the right direction
Even if the ML's doing it out of pity, atleast someone's taking care of MC. He deserves the world(๑•ㅂ•)و✧
