On a certain day, a certain thought came to Japan’s Sun Goddess. ——Aren’t there too many Japanese people being abducted to other worlds? It’s true that the large majority of Japanese are diligent and docile and soft-hearted, which makes them pretty much the best people to ask for favors. “But recently it’s just gotten way too out of hand…… Oh, I’ve got it! Whenever a Japanese person is summoned, I just have to summon an otherworlder!” And now, every time a Japanese person is summoned, princesses and elves and beastmen and whatnot are reverse-summoned. Under the acknowledgement of the government, they begin living in Japan. Today, too, Japan is at peace. And so begins this laidback isekai cultural exchange story♪

Fei Bai discovered through his boyfriend’s trumpet account that he had been wearing a green hat. Not long after the breakup, he recognized the third party in their school coffee shop.

The senior brother is handsome and tall, but it looks like… he’s not a 0.

When Fei Bai thought his ex might be doing zero for love behind his back, he became angry. He decided to take the initiative to seduce this senior brother so that his ex-boyfriend could also experience the taste of wearing a green hat.

The sky’s the limit. Fei Bai successfully seduced the third party. He walked side by side with this senior brother on the campus and bumped head-on unto his ex-boyfriend.

He thought the moment of revenge was coming, but in the next second, he learned that he had flirted with the wrong person. The senior brother beside him was not the mistress but the former president of his father’s company!

Fei Bai originally planned to apologize and run away, but he didn’t expect to be blocked in front of his home the next day.

The man he called senior brother pressed him against the wall and said in a low voice, “You are so good at seducing people. Who would let you go?”
