This authors characters are all strong http://www.mangago.me/read-manga/double_hound/
LET. FUCKING. DAI (i see you mentioned webtoons and this is manga but just hear me out-)
I feel like it's too underrated even tho the story was realistic and i loved all the characters (it's a bit old but the art is freaking beautiful and my god I cried a lot like words can't express how great the character development is in that manga just GIVE IT A CHANCE)
If you haven't read these yet maybe try what lies at the end and moritat, dark heaven or anything from Asada Nemui.
You could try momentum too it has multiple stories and the relationships are really realistic,,,
