My Sweet Boyfriend Can Transform

Heroine traits: otome heroine, adored by everyone, fragile, softhearted.

You Ruan was a college student until she was struck by lightning on a stormy night and transmigrated to the Ultraman universe. She began dating the human hosts of various Ultramen, only to get dumped by one after another, each with a reason that made her see red.

Mebius: “I’m sorry, You Ruan. I’m an Ultraman and you’re human. Our lifespans are too different. We’re not right for each other.”

You Ruan: “So what if you’re an Ultraman? You’re even bringing up our lifespans! You have the longest lifespan of all. If I were you, I’d be willing to give my girlfriend half of mine!”

Cosmos: “I’m calm, and you’re impulsive. We don’t see eye to eye, so we should break up.”

You Ruan: “Right, right. You’re so cold, even the ice on a snowy mountain can’t compare! You’re so aloof that anyone who sees you would have to call you Boss!”

Victory: “I’m from underground and you’re from the surface. We live differently, so we could never be together.”

You Ruan: “I think you’ve spent so long underground that you’ve gotten used to being a nobody. You came up to the surface and lost your mind. Sand must have gotten in your eyes!”

Ginga: “I have two ways of thinking, but you only have one. Our thoughts are different.”

You Ruan: “Thinking, thinking, what are you even thinking about? I think you’re just mentally ill. What kind of nonsense goes through your head every day? Even space aliens would need two kinds of psychic attacks to mess with you!”

X: “I’m data and you’re human. We’re not made of the same substance, so we could never be together.”

You Ruan: “There aren’t many things in the world made of the same substance as you, either. You can spend your whole life with someone just like yourself!”

And there are plenty more waiting to be unlocked. The heroine will turn dark partway through the story. All her ex-boyfriends will have to grovel to win her back.
