You've been friends with Haechan since childhood. From the beginning, he has always looked after you, he doesn't want you to be damaged by anyone.

time continued to pass, until finally you both grew up and Haechan finally realized his feelings for you, he liked you. The feelings continued to grow, and Haechan became obsessed with you, but the problem was, you had a boyfriend

One night, Haechan invited you to his house, you two were used to visiting each other, but this was different. Haechan served you a glass of wine, and you drank it, but Haechan had already put an aphrodisiac in the glass and you didn't know. And that's how it was, that night became a long night, you and Haechan did 'that' together for the first time, he was the first to do 'that' to you, even you still can't believe it

a few days passed, as you thought, you were pregnant. You called Haechan and told him you were pregnant, Haechan chuckled from across the phone and said

"finally, it worked"

You who were originally panicked became surprised because of Haechan's reaction. Then, Haechan said

"Leave Mark, and marry me."
