Rec, NHK ni Youkoso! Recommendations
Both are about young adult people and their dealing with everyday life. Both are realistic, mostly serious stories with a little humour. There is also romance storyline, but also rather realistic, seinen-oriented.
The set-up for each series is incredibly similar; a male protagonist in their twenties starts off in a state of depression until they meet a female character whom would impact both of their lives immensely. Both characters face everyday obstacles in a rather realistic world, adding to the relatability. Each series also has a similar feel, both being a mix of comedy, romance, and drama.
