I have been playing it for a few hours, and I must say, although it has some flaws (IMHO) I really enjoyed it.
Story and characters:
Not much to say. You should not expect a vast, complicated plot with intervening twists. You just follow the daily life of Leanna (in the morning) and Kain (in the evening) to gain money and repay the debt. It is simple and it does its job. More importantly, Leanna, Kain and the others are somewhat believable characters for hentai standards.
Gameplay-wise, there is not much you can do besides walking around and talking to people (And triggering events, and hoh boy, are there many scenes.). At some point you can unlock the quest in the guilds but the mission will only be walking around, collect some stuff and avoid the monsters. I really wish that there was more RPG elements.
Personally, I always try to get the vanilla ending, when I play a ntr games for the first time. So far, I have not found a method to completely avoid sexual harassment to get enough money. The only method I found so far, was to earn money by completing the quest without getting caught.
H-Scenes:
As already mentioned above, there are many ... like a lot. I had personally the feeling that every being with a dick has a scene with Leanna. Even after rushing through and literally playing for hours, I still have not got all the scene yet. Something that did not bother me too much but it might for some: Not all the scenes contain unique CGs but instead it reuses some of its assets.
Final Verdict:
I had a great time with the game. Yes, it has its flaws, but honestly I really enjoyed it and would even consider to buy the game and support the publisher and the developer.
