I know the sruggle. For me it's that I watch so many seasonal animes that I don't have rly time to watch older anime. I finally finished Aldnoah One's first season that I left in the middle multiple months just cause I was constantly behind seasonal ones
I constantly tell myself that no I'm just watching couple animes this season, most of new stuff isn't even that good, but I somewhat end up trying multiple out and then sticking with them.
If u just want one anime to watch this season Hanako-kun wouldn't be bad choice. The art style is so pretty! I actually didn't check Rikekoi, but I kinda don't want to, my quota is full..
