I find this such of story often in seinen demographic. Tho I enjoyed them a lot at first, they tend to make me disappointed. One example that make me disappointed is Aku no Hana. While I enjoyed the story from the start through chapter 33, it turned me off due to a time skip and introducing a new main character. I knew where the story goes afterward and dropped the series. Sadly, I can’t pretend the rest of chapters never existed. I wished it was ended in chapter 33. I checked all of Oshimi Shuuzou works but most of them ended up disappointing as the same as Aku no Hana. I think I understand what Oshimi san tries to deliver in his story and I can somehow relate to them due to my past experience. Tho, as a reader, I find his works to be relatable in negative way and can't bring myself to enjoy most of his works through the end. From many of his works, only Sweet Poolside that I find enjoyable through the end and that such a story is the type that I want to ask for.

So, here’s what I am looking for :
•The story focuses on two main characters which are a female and male.
•Strange relationship between the main characters. The character attached to each other for strange reason.
•If it’s a romance story, I want the ones who interested in each other are the two main characters. I can tolerate if one or the two main characters have a feeling for another character at first but that side characters must be insignificant to the story. And the two main characters end up falling in love with each other.
•No more Aku no Hana. Please no new main characters introduced in the middle of the story.
•No more Onani Master Kurosawa, Umibe no Onnanoko, Sundome or Aku no Hana (once again). One or the two main characters mustn’t end up with another character.
•No gender bender.

Takianna no Honshou wa S na no ka M na no ka Ore Dake ga Shitte Iru is one example that I really enjoyed. And the ending was so satisfying 🙂
