Glad I'm not the only one lol
Lol what are you confused about? I can explain what I understand.
Basically everything re-read it twice and still didn't fully understand. Some translations were kinda weird
Jihoon and Sunjae are childhood friends who are also in a sexual relationship now. People think Jihoon has it all: looks, talent, brains, money, etc but don't like him. It seems to be a mix of jealousy over his close friendship with Sunjae (who's friendly and popular) and his direct, no BS personality. Jihoon prefers to be alone and he's been like that (at least from what we're shown) since high school.
In the present, they've been skipping get togethers and Jihoon didn't want to go to the freshmen welcome party but Sunjae convinced him to go. There, they are reunited with Kiwoong, who was in the same class as Jihoon in their 2nd year of high school. He's a year behind them in college cuz he had to retake the college entrance exam. In high school, Kiwoong was really interested in Jihoon (Sunjae notes that he noticed Kiwoong watching Jihoon since they were 1st years) and often pestered him until Jihoon couldn't ignore him like he does with other people.
Sunjae, despite his friendly personality seems to have a darker side to him. He's definitely very possessive towards Jihoon and doesn't seem to like Kiwoong "stepping in his territory" (those dark looks @__@) and I'm sure he had something to do with Kiwoong osing both their contact info.
You're amazing thank you
Since page 1 I've been confused....
