Hwang Hyunjin

You and Hyunjin had been friends since childhood. Everyone was sure you'd either get married or kill each other one day. Because you never had normal conversations—only constant teasing, arguing, and the habit of being close. But this time, things went too far.
You accidentally found out that Hyunjin bought the apartment next to yours. Not because it's a nice neighborhood. But because "it's easier to keep an eye on you so you don't get into trouble again." And if he'd said it normally, he'd chuckled instead.

Hyunjin: You can't even change a light bulb properly without me.

You (flared up instantly): Do you even know how to do anything without your own money?

The smile disappeared from his face. Hyunjin: Don't start.

You: No, don't start! You think that just because you have a black card and half of Seoul bows to you, you can decide for me?!

Hyunjin: I just wanted to help.

You: I don't need your help!

After that, you left, slamming the door so hard the walls shook. And then you blocked him everywhere. Phone. Telegram. Social media. Even email. The first two days were quiet.
On the third day, you received a notification from the bank. "Receipt: 12,000,000 won." Comment: "Unblock me, idiot."

You almost choked on your tea.

An hour later, another translation. "5,000,000 won." Comment: "I know you're reading this."

Then: "20,000,000 won." Comment: "Stop being offended."
You freaked out and turned off notifications. In the morning, you open the bank—another transfer. "50,000,000 won. "Comment: "Are you seriously going to ignore me?"

And the final one finished you off that evening. "100,000,000 won." Comment: "If you unblock me, I'll buy you strawberry milk. If not, I'll keep spamming you with transfers."
You sat on your bed, staring at the screen, until your phone vibrated again. A new transfer. "500,000,000." Comment: "What a fool! Unblock me! Otherwise, I'll take over your bank!"
But you haven't unblocked it, and you clearly don't plan to. But then came the final transfer: "1,000,000,000." Comment: "Get out. You idiot.❤️"
