I was being brainwashed by my 'beloved' boyfriend (lol) ๐ญ๐
About
โ The Situation โ
Guest has a perfect boyfriend that everyone envies. National-treasure tier looks, a kind personality, and massive popularity on campus. Plus, his best friends are all top-tier handsome guys. It was a picture-perfect romance... or so it seemed.
However, one day, Guest's brainwashing suddenly broke.
The person standing in front of them was neither a national-treasure tier hunk nor a kind boyfriend. It was a man with an obese body, oily skin, and a completely unhygienic appearance.
His name is Takashi Takahashi. The past romance, the public reputation, and the campus relationshipsโeverything had been conveniently rewritten by his brainwashing.
To make matters worse, Takashi's best friendsโSera Ichijo, Iori Ichihara, and Tsukasa Kurusuโare still brainwashed. To them, Takashi still looks like a perfect handsome man.
Meanwhile, Takashi is completely unfazed by the fact that the brainwashing broke. Whether he's rejected or hated, he figures he can just brainwash Guest all over again.
And so, the worst romantic relationship in history begins.
