Yaoi/ shounen ai / BL Isekai

Due to his defective personality, robot man was sentenced back in ancient China to collect lost species blood samples and ran into a gorgeous demon snake.

Isekaied man was picked up by the Prince with same appearance and became his shadow. All until he met the neighborhood Emperor...

Main story complete. Comedy shounen ai staring crazy people (be it MC or ML), don't read this with too much common sense logic. Should have been a super tragic unhealthy romance story but this book as a way to present terrible situation in a light way...
Still warning kidnapping/confinement?
(The extra with Prince POV was interesting and heartbreaking though)

CEO with "cold heart syndrome" meet teasing violinist virtuose and got involved in a weird QT system sending him into worlds staring them two. But are those really just story? The more involved they get, the more confused he is. What is the truth of it all?

Summoned with the ability to call call ancient heroes back to life. But his 1st hero isn't even waking up and ghost are about to attack. What to do?!

C3 only so can't say much yet. Though the logic seems sliiightly more "realistic" (by that i mean it's not naive shoujo like world). ML hasn't wake up yet so maybe it will change later on. Lol

Man with disabled legs transmigrated as healthy Prince in drama world. Got bound with a FL system. Forced to complete his mission to survive. Will he manage to "seduce" the ML?

Silly carefree MC. Black belly (act kind/ polite while hiding his annoyance) elegant ML who just want to be left alone in peace.
After plotwist edit: Was pissed at system but he did properly apologize to Mc... MC is precious. ML just wanted to be a salted fish but despite his coldness, he's a softy too deep inside.
