Passionate for music, two high school boys became friends as they perform in amateur band together, while they discover their romantic affection... to each other. Third boy on the band of four is also in complicated relationships with a boy music performer whose talent he admires. And that's about it.
One main character wears the same facial expression throughout most of the show...
Relationships dynamics between characters is so bad that the show is hard to watch, especially the movie.
Uninspiring and underperforming show seemingly influenced by awesome
Sakamichi no Apollon「坂道のアポロン」 ("Kids on the Slope", 2012)
but not enough to deliver satisfying performance.

Falling in love with someone means you have to expose the softest, most fragile parts of yourself to them. Otherwise, it won't work out.
This anime is good but if you give a trailer it would be better understood..
But what is good about it? Story is profoundly unsatisfactory, characters are unlikeable and the show is too shallow to enjoy, as overwhelming gay motive is not all that interesting.
Trailer could be found on Myanimelist page which I referenced. However trailer don't give a just impression about this show, IMHO. Problem with trailers is that they usually just try to bait viewers rather than give accurate impression of the show or a decent sample of it.
