PLEASE. Don't trust everything from the spoilers here who have only seen the raws of manhwa. Andante has no significant relationship with Eugene. They may have a-not-too-significant past with each other but they have no further and future romantic interactions.
And MC was not graped by the past esper he handled whose name is Detri. Yes, he was SA'd at some point but only some kind of touching and skinship. However, aside from that, MC suffered a lot from that bastard. No proper meals and can't go outside and so, so much more. He knows absolutely nothing about the outside world aside from those that Wren told him before. Wren is the esper who saved MC from Detri.
EDIT:
THIS IS A SHOUNEN AI.
ONLY SIDE STORIES ARE SPICY.
NO CHEATING.
LOTS OF MISUNDERSTANDINGS.
NO GANG GRAPES.
NOT A HAREM.
HAS A LOOOOOOONG CHASING ARC.
NAIVE MC BUT VERY, VERY VALID PAST.
REDEEMABLE AND GOOD ML.
HAPPY ENDING.^_^
If you want full-blown spoilers, here is the link to my other post with as much spoilers as I can give. There are a lot of spoilers too with my replies that you can read so you won't feel the need to ask the same thing again. That's all!

LOL. I CAN'T THE COMMENTS ABOUT ANDANTE GOT ME LAUGHING SO HARD. Enjoy while he is still like this cause you will pity him later. He will become so pathetic. It doesn't fail to amaze me how I always see comments hating Andante at first but ended up hating Jin Hyo-Seop at the latter part of the novel. I hope that won't be the case because both had their fair share of bad characteristics but a lot of people ended up being hypocrites at the end of the novel.
Where can I read the novel
how can people hate on mc he has rights to do that all things to andante
