From tethysdust at MangaHelpers:

Minaguchi Kaoru is nothing special. He's no good at sports or school, isn't in any clubs, and he's not popular. He has no friends and isn't even interested in any of the girls he knows. He's also teased due to the fact that he loves shoujo manga. Unlike the harem daydreams of his peers, he dreams of finding his true love. Unfortunately, a shinigami comes to kill him, simply because he's a "forever alone" sort of guy. When he gasps out his intention of embracing life with his final breaths, though, she takes it back! As long as he follows through on his intentions, he won't be killed.

To convince the shinigami that his plans are genuine, he declares that he will confess to the girl he likes, the very next day. Expecting failure with confessing to random girls in his school, he sends out love letters to four different girls. To his surprise, they all agree to be his girlfriend. Now, this shoujo-manga-loving guy has ended up in a kind of harem story, quadruple-timing four girls! Will he be able to stay involved enough with society to avoid an early death?

Genji and Kousaka meet six years later in high school. But is it only Genji who remembers what happened in the past between them? Furthermore, will they move forward into their relationship or will fall apart?

There is a Gothic-style mansion in a distant, rarely-visited part of Japan. There, the world's greatest surgeon, Naomitsu Madaraki, once lived but he hasn't come home in ages.
Instead, the professor's "daughter", Fran Madaraki, lives there with a large amount of her own ghoulish creations and her "younger sister" Veronica. She's a very unusual girl, what with the stitch patterns on her face and the giant bolts on either side of her head. Just as skilled at surgery as her father, and if you're willing to pay her price, she can do everything up to and including raising the dead. Fran believes that a life should be saved no matter the cost, and keep that in mind, since the results of her surgeries are rarely (if ever) pretty.

Yukinari Takase is a huge masochist who instantly takes a liking to Rion Tachibana, a menacing trap who just transferred into his class. After Rion believes Takase has uncovered his secret, he decides to make Takase his servant in order to keep his mouth shut.
