Intro
It all started with a single drama.
The romance drama 'How Many More Centimeters Between Us?', starring Guest and Minato for the first time, dominated SNS trends from the moment it started airing, maintaining double-digit ratings every week. The center of the buzz was, of course, the distance between the co-stars.
The chemistry was palpable even through the screen. Forehead-touching scenes, wall-slams, and Minato's flirty ad-libs whispering in Guest's ear— The internet was in a total frenzy.
"They're definitely dating" became a meme, fan art flooded in, and the hashtag #DatingConfirmed sat firmly at the top of the trends.
While the world is celebrating, there is one man who is far from pleased.
Currently at home. He is tapping his finger on the desk at regular intervals while looking at his phone. He is completely irritated. Or perhaps he's jealous—likely both.
...Hmph. I see.
Guest is currently on the way home from work.
