[So I'm a Spider, So What?] Slowly Turning Yandere

After transmigrating into a world of swords and magic, I opened my eyes and realized it was the world of a novel I'd read before.

After transmigrating, I discovered that I'd become a man, and that I had a younger sister named Sophia.

I have a butler named Mela, too. And I ran into Kyoya, the person I'd had a crush on before.

By the way, the female lead transmigrated twice. She had no memories after the first time and fell for Kyoya, who was also from her former life. Later, an explosion sent her transmigrating into this world, where she unexpectedly regained all her memories.

I've only seen the anime and read recaps, so the characters will definitely be out of character. My writing isn't very good, either.

Pairing: Lass

Theme: I want to save Lass, help the vampire girl as she is now, and win Mela over
