My god this was so sweet and light I think I strained some face muscles from grinning so much.
This show's premise may be nothing new, but it manages to depict the struggles of falling for your best friend and the sheer, horrifying exhilaration of first love so well, it borders on perfection.
At first I was a bit put off by the almost aggressive wholesomeness of the series and the constant sparkles every time something vaguely romantic happens, but dammit they won me over alright.
The writing is genuinely great and the entire cast delivers such engaging and believable performances that it's a real challenge not to fall in love with the characters.
They're all just such good kids, trying their best to be there for one another and I really can't think of any way to describe the whole thing other than "genuinely heartwarming"
There is essentially no external conflict in the series, no antagonists, no dramatic plot twists, nothing of the sort. Instead, the story focuses on our two leads figuring out their feelings and learning how to communicate with one another, giving each other space to process their changing relationship and carefully consider their choices all the while.
One slight trigger warning I have to mention, however, is a scene in which one of the characters doesn't stop his physical advances on the other until he's been asked to stop three times.
Personally, in light of how well the fallout of this event is handled and how deeply loving and respectful the characters' relationship is overall, I found I could just about stomach that scene. If you are sensitive to these issues, you may want to proceed with caution though.

All in all, if you want to see an incredibly soft, yet grounded high-school romance reminiscent of beloved classics such as Kieta Hatsukoi and Kamisama no Ekohiiki, or are simply looking for a light, wholesome rom-com to while away a rainy day, then this show is perfect for you.
