I really liked this and thought it was cute. Short and sweet with not much plot bc it's basically an add-on to the manwua. You don't need to read it to watch this, I didn't. definitely romantic with no conflict whatsoever. Pure fluff. Its literally like 15 mins maybe. The art style is simple and clean and very beautiful. I think the limited colors really add to the whole "this isn't a full story but just a piece of their life together" vibe. You can really tell who the characters are even with such limited run time based on how they look and how theyinteract with each other.

I like how it wasn't a super dramatic romance, and it showed playful banter between the two characters like what would be in a real relationship.

Def rated PG-13, especially the 3rd episode. There's nothing graphic but just a warning I suppose. Nothing is shown or explicitly said.
