Yes, besides of this little unamused experience for me, I was enjoy the VN ~ and even gave you 5 star rating.
You should check in internet the sea house from the TV series "Heated Rivalry" and you may see, why I was brought it up too. Some parts are matching perfectly with the house in your story.
And I don't really have one favourite now, the game is still in such early progress, and it's hard to say which character I would choose for the love story.
If it's only about the look and charisma, then this is my personal ranking:
1. Romeo
2. Daemon
3. Taehyung
4. Jett
But that's sure swap in future, if you add more personality and stories about each character.
