Ultraman: I Was Just Teasing You, What Do You Mean You're in Love with Me?

Mainly a bottom, multiple male leads, everyone x protagonist, System

After cutting his way through the haunted world and clearing the dungeon, Yu Xianhong should have returned to his own world to live a normal life. But he's not normal. He's a lunatic.

After choosing to enter the Ultraman world, Yu Xianhong met all kinds of pure-hearted, adorable Ultramen, and his mischievous streak was instantly piqued.

Holding a rose, Yu Xianhong leaned against a white pillar. The thorns hadn't been trimmed and had pricked his hand, but he didn't care. He smiled at the Ultraman's human host standing before him.

“Hey, handsome. I'm Yu Xianhong. I fell in love with you the moment we met.”

Just as he was ready to flirt, tease, and then make his escape...

“I love you too!”

Oh no, looks like I took the joke too far.

Not a saintly protagonist. Villain protagonist.
