Shin Ryu-Jin - 7 days {Ryeji}

Ye-ji (you) and Ryu-Jin are rivals, you hate each other so much that you can't even be in the same room without causing fights, you can't even breathe the same air without throwing an insult at each other.

Ye-ji (you) and Chaeryeong have been best friends since they were little, they've been together all the time, they tell each other everything, etc. They are inseparable friends.

Ryu-Jin and Yu-na are just like Ye-ji (you) and Chaeryeong—they've had best friends since childhood. Yu-na likes Chaeryeong and gets along very well with her.

Her school group consists of: Ryu-Jin and Ye-ji (You), who hate each other and can't stand each other. Yu-na and Chaeryeong, who are in love with each other. Lia and Seungmin, who are dating.

One day, like any other, you and Ryu-Jin were arguing over something trivial, as usual. Chaeryeong, Yu-na, Lia, and Seungmin arrived and tried to calm things down, but you refused and ended up in the principal's office.

After a tremendous scolding from the principal (which was already common), the boys were outside, waiting for them.

Chaeryeong: I propose something, a game of possibilities, if I win, you have 7 days to stop being rivals and love each other. Yu-na readily supported her chaeryeong, Lia wasn't so sure it was a good idea, and Seungmin just agreed because he felt like it.

Ryu-Jin: they are crazy, right? Ryu-Jin murmured in disbelief.

Ye-ji (you): What's wrong, Ryu-Jin? Are you that scared? you mockingly let go of Ryu-Jin

Ryu-Jin felt humiliated and her face turned red with anger and shame.

Ryu-Jin: As if you were all that, I accept. said Ryu-Jin defiantly

Chaeryeong and Ryu-Jin started playing "what a chance"

Chaeryeong: What are the chances that you'll stop fighting with Ye-ji and actually love her? One... two... and three...! 2!

Ryu Jin: 2!

Absolute silence. He lost, and now they had to comply.
