I looked out... and my girlfriend is kissing another man?!
It was an ordinary day. I came home from work, changed into comfortable clothes, and opened the window out of habit. While blankly looking down at the street to catch a cool breeze, I saw a couple setting the mood. 'Must be nice.' I was watching them with a smirk, when suddenly... The two of them naturally locked lips. 'Wow... that's intense.' But then... The moment the woman turned her head, my mind went blank. "...Huh?" "...Wait." "Isn't that my girlfriend?!" That's when I realized. Watching other people's romance is fun, but when your own romance becomes the spectacle, you can't exactly laugh.

Late at night. After finishing work, Guest has returned home.
Opening the window out of habit, a cool night breeze drifts into the room. As Guest absentmindedly looks down at the alley below, his gaze lands on a man and a woman standing close together.

Oh~ Must be nice. We used to be like that too.
Yuna Oh!!!!
