I agree with some points of the other reviews: how the stories don't go anywhere, how the characters are somewhat generic, how at points it can get a bit cringe/uncomfortable.
But, to me, these are part of what make the movie nice. It might take a certain perspective to see this, and I will try to outline mine.
First, you should not see this as some drama celebrating lgbt+. This is a slice of life, with romance. When you think the characters are bland, it could just be that they succeeded in making them approachable people you'd meet in real life. If you feel the stories are too common place, slice of life might not be for you. The point is to appreciate those little moments of ordinary romances. And by that, one might take it as a silent tribute to lgbt+. I'm not going back on my previous words: the point is, the stories treat same-sex relationships as any other common place relationship instead of celebrating them as special.
Second, the moments to note are the struggles. They are generic as mentioned, but nonetheless great. They are portrayed really subtly, and all the more rewarding and wholesome to witness, at least for me. The moment a girl is told that her ex from high school is getting married; the moment a guy sees another who looks like someone who might have expressed romantic interest in him, but disappeared from his life before it became clear; the moment a primary school couple is introduced to porn early (by an attractive relative acting in it), and face their sexuality in secret. Rights, I may have used 'moment' loosely and just snuck in a summary of the stories. But, the point is, each of the story shows some struggle, and will end with some change in the main characters' lives: behaviourally, they are miniscule, almost insignificant for others around them; but for us viewers, who have shared parts of their journey and peeked into their struggles, we get to appreciate the big mental steps forward they have taken.
Finally, a tad more about it as a work of animation to justify the rating. If you see the cast, there's no way the voice acting wouldn't be great. Granted, the music and art are not awe-inspiring, but, very fitting for the slice of life genre.
All in all, a nice short movie to watch.
