A Straight Guy Transmigrates. System! How Did He Fall in Love?

Two male leads + System + pure love + modern romance + CEO + both are virgins + happy ending

A 185 cm tall, handsome, domineering CEO pursues a 178 cm tall, stunning straight man.

Lin Mu was straight. He died saving someone and transmigrated onto a bed. The terrifying part was that there was someone else in the bed, a man, and it seemed they had done something unspeakable together.

Lin Mu: What's going on?

System: Complete the mission and you can go home!

Lin Mu: What mission?

System: Marry Gu Ziyi. You can go back once you put on the wedding ring.

Lin Mu: What the hell! Is he straight or gay?

System: Straight!!

Lin Mu: No way. I'm changing the mission. I'll count it as complete if Gu Ziyi marries a woman!~

System: All right, then. Since this was our mistake, you can go home as long as Gu Ziyi gets married!

One year later...

Lin Mu: Damn it!!! Who can tell me how Gu Ziyi ended up gay?!

And more importantly, who can tell me why he's chasing after me every day, begging me to marry him?

A straight man transmigrates into another world and gets a marriage proposal from a domineering CEO, with the adorable little System 009 caught in the middle. Will he go home, or stay?
