This anime is not meant to appeal to every single person. The overall story is a bit cliché as the idea is overused. Falling in love after being with someone for a long time, that has been overused in many animes. It's time that we stop that.
Despite all that, the anime saves itself by adding interesting and slow progress through the characters bonding as they get closer and closer. Sometimes it gets more awkward and awkward.
Without spoiling too much, if you like a laid back, less serious, chilled out, funny, comedy like anime, then this anime is perfect for you. Be sure to watch the second season as well!
