Jeongin is heavily affected.

Despite knowing it's his fault for breaking it off with you out of his insecurities impulsiveness of you deserves someone better, it's weird that his heart still yearns for you.

He misses you.

The way it's been a year and he still went out and bought a cake for each special event; your birthday, your graduation, your anniversary.

He could do nothing but sit on the table of the café silently, hoping you'd come back to him when he blows out the candle of the cake.
