This anime is definitely underrated, but the end can be a bit disappoiting (as many animes unfortunately) This anime is quite psychological. Of course, it's a "dirty" ecchi where you mainly follow the adventures of 2 guys (I skip the 3rd one who is useless), but given the situation they're in, it's not a simple "Enjoy and have sex with who you want". There's moral choice where you can ask yourself "What would I do, in their situation, if I was them ?" It's not the best anime available, the plot is clearly underdevelopped (while the potential is just huge) but still, it's enjoyable and as Isaid not so simple. In that sense, I tend to recommend it
