I think it MAY have been a isekai or isekai like genre. Maybe reliving life again and again situation? Videogame like? I want to say the main character fell in love with a servent/butler/assistant. Main character was like the only one "aware" and i believe the love interest starts to become "aware" as well. I think there is suicide at some point right in front of the love interest which shows he has feelings as well.
