There were 3 main couples that occupied this story and had time each on chapters. The MC (XW) and ML (Klaire) of course, Carlo and Aiden, and Craig and Randy (Aiden's father).

Why?? because I noticed that Klaire may be a bit uncertain of their future because of XW's rejection towards him, but later on XW also discovered his feelings waaaaay too soon? for Klaire. Idk, its just that he suddenly (?) realized after ML was gone (?) and he began to accept him even though reluctantly still. I could understand. Anyways, I still love MC and ML, especially Klaire's perseverance and XW's strong and willful personality even though an omega himself.

It was kinda weird how the whole novel the MC didnt show any obvious signs if loving the ML, but then when the ML goes missing after their fake engagement, he suddenly realizes that he has lived the ML all along.

Such as Xi Wei's (mc's) sister joining him at school. She was supposed to attend the school two years (i think?) after he started which means that they would attend the school for 2 years together. Xi Wei misses his family, and asks to meet them often in the book, but the sisters arrival at school was completely forgotten and not mentioned at all as if it didn't happen. I found it a little bit disappointing. Although it's a very small detail, since she already said herself that she would attend the school, and the book actually put some focus onto it, I thought it would be mentioned at least briefly...
