SPOILER ALERT
Basically his brother wants Jaehee and Daojun to break up (his "secretary" should run Jaehee over once). So another idea to do this was in the recent chapter to make Daojun live with his b-uncle again ALTHO HE KNEW the uncle took Daojun's child support money to save his company which went bankrupt anyways. They met in an Restaurant and the brother told Daojun this (who didn't know) after Daojun wanted to call every contact quits.
For Daojun it was a shock bc he found out his uncle was abusive just because and Daojun had to break up with Jaehee before over nothing. He was scared his uncle would hurt Jaehee if he found out he was the one Daojun gave his scholarship up to. Daojun really thought the uncle was mad because "Tuition was too expensive" but the child support had been so much money, this would've been no problem. But the uncle is simply an A-Hole.
So in the end Daojun took some champagne and splashed it into his uncle's face. But the face Daojun made right after was really scary. (Little Yandere like. I'M WORRIED he made this face before too 1. When his brother tried to run Jaehee over or act like it to scare him off and 2. When his cousin threw Jaehee's tie and shoes (The last thing he had from Jaehee when they broke up) over the balcony, spoiler too: He jumped right after... Jaehee caught him but now has Amnesia (He still loves Daojun tho just forgot all the time they dated, and the bad break up too))
Why did I mention this as well? Those children especially Daojun had to endure so much
Everyone in Dojun’s family is just so consistently cruel to him for no good reason. F them, he’s my son now, I’m adopting him.
