Really charming and short read. Olga is truly lovely. So are Katusha and Niko in their own ways haha. I'll definitely check out your other VNs too!!
I loved Niko's theme the most, but I found the soundtrack so memorable as a whole; each of the ending themes were perfect for their respective scenes and the other tracks captured the setting pretty well.
The art is really nice overall, but wow, that post-credits CG in "You Are My Love", that one was so incredibly gorgeous!
Oh and I must mention that stomach sound effect was so funny lololol it's great
