The MC works very hard because he has to manage his comatose sister, and had to deal with his parents passing away in an accident. He is very optimistic and he pursues the ML for a majority of the novel. He falls in love with the ML when he notices how kind and gentle the ML sounded when he sponsored for the MC sister.

Although the MC is very sunny and bright, he has a lot of insecurities, which the ML deals with a lot of care and affirmation

Btw f*ck Song Chi

About the ML, he was sick for a lot of time which made him very unreactive and paranoid, plus he very rich and famous, so I understand his attitude in the initial stages of the novel. But he talks it out and fixes his shortcomings.

MCs sister gets well and even does her college. Also the smut might seems forceful but the ML always confirms that the MC is ok with it either before or after it, after they establish their relationship. And even when they were not in a relationship, the ML was not raping the MC.

All the misunderstandings seems reasonable when considered from both povs. Overall read this novel if you like the trope of cold and overbearing ML, but done right.

they accepted the relationship right away, literally one of the first times I’ve seen such chill parents in a BL set in modern times. Granted homos*xual marriage is legal in this society, but still a pleasant surprise! Even if the grandpa beat up ML still lol
