Of course. Who needs a porn game to have sex scenes? That would be ridiculous
As I've written already I view this more as a harem/slice of life- Manga/Manhwa/Anime made into a VN with some IMO positive improvements.
First the MC: He has this typical Anime-Protagonist hair and his character and looks reminds me of the protagonist of "My Teen Romantic Comedy SNAFU" "Hachiman Hikigaya".
Hachiman too doesn't really give a shit and it takes forever before something intimate does happen.
Only this MC is a tad more edgy and doesn't get flustered at all (which is good in my books).
There is a ton of fanservice (just like in a Anime/Manga) humor, obligatory competetive school sports,
a Tsundere (Bella),
a (non related) sister who is (not so) secretly into the MC (Nami),
bullies (Nadja and Zara and hopefully formally Bella),
a Kudere who is calm and collected but still interested in the MC (Sasha),
a Dandere who is always shy in front of the MC (Sonya),
a Megadere who shows her affection very openly to the MC (Victoria/Mila),
a Deredere who tries to act friendly and positive all the time (again Victoria/Mila but they have their depressed moments),
the obligatory hot milf of a love interest (Amber - mother of Bella)
and finally the love interest from the past who either died, got lost or had to move to another city (Summer).
Sex scenes will (hopefully) come but my experiences with anime and Manga lead me to believe that it will take a looong time.
(Btw I had to research all those -deres and only a Yandere - basically a psychotic stalker or extremely obsessed psychopath who appears normal on the surface is missing but I could imagine that Zara (or Nadja) could evolve there with her already crazy tendencies and her not so subtle look at the MCs pants)
