One Moo'r Plow - Chapter 61Book 1: : The Coming Storm.

Klein’s greatest wish is to transmigrate to another world and live life in an isekai, just like in anime, manga and novels. However, fate is on his side and the typical truck that the main characters always carry in isekai runs over Klein. But, to his bad luck, he lived a few more days in the hospital and, just on the day he died, Klein heard a ⟨⟨-DING-⟩⟩ that he knew it meant. That was the day of his death, but also the beginning of his adventure into another world.

A replica of Marquis Kieran Vale, the son of the Marchioness of Vale, who she deemed a failure. That was all she was. No, she was now referred to as “he.” At least until she met Claude Del Ihar.

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?”
