This is a surprisingly wholesome story of two college students getting drunk and ending up in a situation which leads to their subsequent marriage. Spoiler: It is not pregnancy. There are misunderstandings but nothing in the level that would make the story a annoying or a pain to read. The misunderstandings are innocent and the kindness of both the male and female protagonists make it such that there is no escalation and that those are resolved peacefully. In short, the characters don't disappoint. The only minor nitpick would be an accidental grope in a later chapter but it is nothing major and is played as a joke.Another spoiler: The story has no traces of NTR and the characters are wholeheartedly devoted to each-other. There is no room for doubt about that.
