A gaslighting alien parasite taking over my unrequited crush is fine too.

one problem in hentai sex can't cure. I guess an alien parasite is fine too.

having a devoted parasite in exchange for a girl who doesn't like you is fine too.

At least it ended so Masaya doesn't have to worry if he'll be food next.

In other DATE's and Taniguchi-san's similar works the friend / boyfriend / unrequited crush is killed after the intercourse by the parasite / demon / spirit of a serial killer (only in the alien slime multiworks the main protagonist is saved). The parasite states that brain tissue is tasty, so Masaya is in danger.

@ElisaG maybe endorphins released during sex are more tasty than brain tissue?

@tonythetiger endorphins are produced by a gland that it probably ate too.
