Well, we're off to a good start with this one, bois. Quality MC, confident, decent-looking, fit, knows how to flirt without looking like he's about to faint, there were no "milady" cringe words in the conversations he made either, a very good cast of attractive female characters (Kelly and the bitchy CEO are my favorites) with different body proportions (I'm more into thicc, busty ones, so don't really care that much about their proportions tho), some good humor here and there, and an interesting premise about the MC doing his own investigation into his sister's disappearance. Oh, and the biggest plus, there's no questionable shit like NTR in the story.
The few things I'd like to point out as minuses that need to be fixed are the lack of a save function while texting/sexting with the girls, the fact that there's only three pages of saves, when there should be more, and the voice acting, which is a hit or miss. I personally liked it, but other players might not.
Overall, it's a very good start for a first release, hopefully, the dev has a good release schedule for their updates too. I know I'm definitely looking forward to seeing how the story unfolds.
Best of luck to FXLS with their project !!
