This manga is just a shoujo that gives you exactly what you came for.
Also there are so many light filters and sparkly effects, I think you'll die if you turn it into a drinking game for each effect. Characters are cute, MC is kinda lame and fragile, guy is chill and stoic, the more straightforward type if you're into that. Rival's kind of creepy but bearable.
I basically mainly read it for the MC's friend cause I like side romances more that the actual romance in all honesty.
Romance is eeeehhh okay. It's not the most character driven or very interesting but it's fairly okay. The art style is really cute, and might be a reason for you to stay.
I'm giving character an 8 because I have a huge bias for energetic girls like Nico.
Again, you come for the cute romance, you stay for the cute romance.
