I'm looking for a slice of life, found family kind of drama that revolves around the same school club (high school or university is fine) or the same sports teams, etc. Similar to Racket Boys perhaps. Anime loves to do these: K On!, Free!, The Melancholy of Suzumiya Haruhi, Kokoro Connect, etc.  

I'm normally a romance fan but I not necessarily looking for it at the moment, slight romance would be a plus.

It doesn't necessarily have to be a youth drama either, I'd take an office drama that revolved around a tight knit group as well (though business related dramas are hit or miss for me). 

  • Rookies
  • Tumbling
  • Aogeba Toutoshi
  • Suikyuu Yankees
  • Yowakutemo Katemasu
  • Gokusen
  • GTO
  • H2
  • Ouran High School Host Club

You HAVE to watch Twenty-Five Twenty-One, it meets all your criteria, plus it's really good 

You can also watch Eulachacha Waikiki, it's a very funny drama and I really like the atmosphere.

Falling Into Your Smile (esports/found family/romance... nothing bad to say about it)
