Quick Transmigration: The Beautiful Cannon-Fodder Keeps Getting a Happy Ending with the Male Lead

Content warning: This story portrays the original bottom in a negative light.

Zhang Dai has been able to hear sounds no one else can since he was a child. He thinks he must be a hero like Ultraman, destined to save the world, until one day he really does end up in another world.

Except someone else is the one saving the world, and he's just a little cannon-fodder character they happened to pick up along the way.

[World One]

The young master in an ABO story: Zhang Dai grew up with almost no parents around. He thinks that someday he'll have to find himself a family, so he picks up a stray-dog-like man from the roadside. But can someone tell him why this little dog bites?

[World Two]

The laid-back CEO who thinks he's an E: Zhang Dai believes that being an E in this ABO world must make him a total trump card, until he experiences his heat. Can someone tell him why an E has a heat, and why is the man biting his neck an O?

[World Three]

The old-fashioned Beta teacher: As soon as Zhang Dai starts his new job, he's assigned to teach senior-year students. He thinks his days will just pass by in a busy blur, but he keeps running into the parents of students in his class. He thinks things will get better once they graduate, but when did someone move in next door?
