Phenomenon game. First erotic VN where I actually read through the dialogs instead of skipping through everything to get to the sex part. The interactions with all the girls, while not always realistic, are all very wholesome and sweet. I played through it twice, the first one for gameplay and the second for completion. However, it'd really help if we get a visual notification every time a choice increases the love/lewd meter instead of having to check every time.
[Edited] I found the way to unlock those 3 CGs. Too bad we can't discover the kink of all the girls for now. Still a good game though.
I expected Sophie to be an annoying character with easiest-to-unlock CGs, but she turned out to a on par with Yui on the scale of cuteness.
