Hentai in general is often far from any kind of believability in relationships, but here the turmoil seems particularly acute, perhaps because of the strange "sort of dramatic" plot. A little about him. School in the middle of the school day. An earthquake. The ruins and four survivors. Two boys and two girls. One of the boys is "bad" (or rather lustful) forcing first one, then the other girl to have sex. But they both like the "good" boy, so they slightly-slightly resist the insidious villain, while suffering a little remorse in the process. And it doesn't matter that all around are solid ruins - rubble and broken glass, that the exits and stairs are blocked, that there is no food and water, and in the piles of stones you can see the corpses of classmates. We're watching hentai. A drama about losing your virginity... ------------------
