It seems I really messed up. In more ways than one.
A long public confession KakaoTalk message sent by mistake to the 68-member group chat of the Namyeon University Economics Department.
I had no idea that a single mistake would shake my life to this extent...
They say the price of innocence can sometimes be incredibly cruel.
Lee Hyeyeon, the class representative of the Namyeon University Economics Department, was the one who made my heart race like crazy, even though I had never dated anyone in my life.

Falling for the mischievous pranks and egging on of my peers, I ended up conveying my feelings to her in the worst possible way.
'Namely... in the form of a public confession in the group chat.'
The moment I sent it, the atmosphere turned cold. I felt so much shame I couldn't even lift my head.
But then, she left a single message in the chat... one I couldn't believe even as I saw it with my own eyes.
"Yes, I'd love toโฅ"
Lee Hyeyeon, the idol of the Namyeon Economics Department and the 'Happy Virus' who is kind to everyone.
The reason she accepted such a ridiculous confession... wasn't out of simple pity.
She says she hasn't taken her eyes off me since orientation day.
Behind the mask of a bright and cheerful class rep, a chilling desire for monopoly and obsessionโhaving longed for and observed only me for a long timeโwas hidden.

"If this was a joke... Senior... you don't want to know what would have happened to you today."
"That look in your eyes when you watched me for so long... did you think I wouldn't notice?"
She smiles brightly and leads me by the hand, her touch warm.
However, within those pink eyes, a deep sense of possessiveness and obsession was flickering.
In her suffocating love that doesn't even allow for casual conversation with others, can I continue this sweet yet terrifying campus romance...?

...The incident started from something very trivial.
It began with light venting during a drinking session. Egged on by the mischievous teasing of my peers who felt 'sorry' for me for never having dated at my age, I ended up sending a long public confession KakaoTalk to the class rep, Lee Hyeyeon, whom I had liked for a long time.
If I could go back to that moment, I would slap myself across the face and desperately scream this into my own ear:
"If you're going to do it half-assed, don't even think about trying!"

A parade of cringeworthy lines and typos that I could barely look at.
While everyone in the group chat was stunned by this horrifying public confession, the reply that came back from Lee Hyeyeon was a single sentence that defied everyone's expectations.
