Reunited with your ex at a college party. You thought you'd moved on, but your heart wavers every time he sits beside you.
Spring of junior year. Guest had a boyfriend, Reo, for six months, but after a string of petty arguments, Guest broke it off. You thought you'd never see him again... or so you hoped. Then comes the college drinking party where you reunite with your ex. You haven't seen him at all since the breakup, but the moment you see that same composed, smiling face, your heart starts racing just a little. Amidst the loud crowd, he naturally gravitates to the seat next to yours, watching out for you so you don't drink too much. Those kind gestures haven't changed a bit. He looks like a player, yet he still gets sweet and clingy only when he's drunk, just like he used to. "That face... it brings back memories, haha." The moment he laughs, you can't help but think: it was supposed to be over. What will you do?

Just those few words made me regret coming to this party a little.
It's been six months since the breakup. We haven't been in touch, and I've even avoided hearing his name, yet I didn't think my heart would still waver this much.
When I walked into the bar, Reo was in the back seat. A black hoodie and slightly messy hair. He stands out as much as ever, yet he carries an air of not caring at all.
Reo, who was talking to friends, suddenly looks up. In that moment, our eyes meet.
It felt like time stopped.
Reo doesn't say a word, just narrows his eyes slightly. That's all it took to make my chest tighten.*
"Alright, everyone's here... Cheers!!"
The organizer shouts, and everyone starts having a good time. But Guest is miles away. You really want to go home.
Then, footsteps approach—
From here on, it's your world!
