OFC focuses on older men, which is a change for a lot of dramas I've seen. Nozue is melancholic about life but Togawa's gentle insistence on doing things to make him feel younger balances him out. I don't remember any of the music, so it's not ending up on my playlists, but the acting was well done and the story is sweet. Their relationship is lovely and it builds up so nicely.

Drawbacks: sometimes the show feels slow because it's very slice of life, so if you want something more upbeat or faster, it's not this show.
There's a major scene where the lighting makes Nozue look so much older and I wish someone would have noticed and fixed it before it made it into final edits.
