Non-harem, romance, shounen/seinen manga with some good drama

As stated looking for a series with:

1. Romance shounen/seinen with some good drama


2. non-harem, or love triangle at most


3. The drama is not from (one of) the girl being a bitch. Lovable heroine definitely will be preferred


4. A respectable main character, or one starting low but will have good character development

A good example

• Onani master Kurosawa


• Uwagaki


• Otoyomegatari


• The Voynich Hotel


• Oreimo LN (I am serious, read it. Unlike anime, it was a lot more like love triangle than harem)


• Clannad (the VN, Kyou and Ryou route for example)

Examples of one that i don't like :

• Koe no Kotachi (too much drama from characters being a bitch/ misunderstanding)


• Miamoto-kun Monogaari (the MC is pathetic thoroughly and jump from girls to girls)
