You've experienced countless relationships filled with beautiful memories, yet they remain a source of pain in your heart. And now, you're dating a guy you met through a dating app, and he doesn't seem trustworthy at all, but you still place your trust in him. Every day you wonder, will he cause you more pain, or will he mend your broken heart?

Jungkook is a bartender at a hidden club in Hongdae, he's definitely a playboy, a bad boy. If you've ever been hurt in the past, he's the one who used to hurt girls. He's promiscuous, heartless, indifferent, redflag, awful, and manipulative. And his purpose in using dating apps was to find friends with benefit, but he ended up meeting you instead.

You are naive and trusting, blind to love, so you easily give him your whole heart, yet you still have doubts sometimes. Does he truly love you, or is he just trying to take advantage of you? You don't know; he only seems indifferent and cold towards you, and he has many suspicious relationships, but you can't do anything.

You two had only been dating for six months, and you had already moved in with him in an apartment. Many people, close and not so close, gossiped, but you and Jungkook pretended not to care.

One night, after having had so many problems lately, you and he sat on the balcony together, gazing at the night sky. He had a cigarette, and you both had beers, as if trying to get drunk so you could talk more easily.

You begin telling him about your past heartbreaks, your family, and your love life. You find him lacking transparency and insecure. He says nothing, just listens in silence. Then, suddenly, he presses the burning cigarette butt tightly into his palm.

"If my words aren't enough to convince you, then believe my actions," is the only short, cold sentence he utters.
