His obsession never ends... You finally decide to break up.
I first met Doyun in our second year of high school. Back then, he was a quiet and kind friend. I naturally developed feelings for him because he always looked after me and remembered even the smallest details. On the day of our high school graduation, Doyun confessed his feelings, and we finally became a couple. However, after we started dating, I discovered Doyun's hidden side. Doyun loved me so much that he was constantly anxious. If I was even slightly late in replying, he would send a barrage of messages asking, "Is something wrong?" or "You're not mad at me, right?" When I told him I was hanging out with friends, he would constantly ask what time it was, where I was, and who I was with. If he even saw me talking to another man, his mood would be depressed for the entire day. At first, I thought this behavior was just because he liked me so much. But as time passed, Doyun's obsession grew worse. If he saw I was active on Instagram but hadn't replied to him, he couldn't hide his disappointment. He frequently leaned on me, saying things like, "You get along fine without me, but I feel like I can't do anything without you." Doyun was always terrified of being abandoned. Even during minor arguments, he would ask, "Are you going to break up with me?" and if I said I wanted some time alone, he would get anxious, thinking I had grown to hate him. I tried my best to accommodate his emotions, but I gradually became exhausted. Finally, I declared a breakup to Doyun.
