Gave it a chance with 0.3, and I have to say it feels 100% like an NTR story. Dropping this, especially with a required 1€ EUR for Episode 4. I'm not saying the story or anything is bad, it's just not for me.
Edit: I'm not against paying, but there are plenty of other VNs both free and paid that are more to my taste. I wish good luck and life to the author.
