On the battlefield, the Avengers fell into a bitter battle, and when Thanos was about to win, suddenly, there was a loud noise in the sky, and only a huge battleship that covered the sky appeared above everyone’s heads, and opened the door from the battleship. A man stepped out of the hatch.

“who are you!”

Thanos felt uneasy and shouted loudly.

“Who am I, you ask?”

The man looked down on the world.

- Description from novelbuddy

I was reincarnated as the supporting character of a novel. As a wingwoman in a depressing romance novel titled at that. Romance is out of the question, and the future of my family is ominous because of debt. I was going to become a civil servant to gain some of the splendor I never got in my last life…but the male love interests are acting kind of strange?! “Just think about it, does Shushu look like someone who would blush and act shy?” “Wow…….that would be great.” Cory said as he stared at Hylli in a daze, and Yves frowned and whispered to himself. “Should I just kidnap her…….” Swan wrapped his face with both of his hands and stayed quiet. His face turned bright red. The blush turned his ears red. Why are you guys fooling around, you’re supposed to be obsessing over the heroine. The story of Shuraina West, Shushu’s reverse harem academy survival. Note: Ojakgyo means wingman/woman!
