This is the very first anime I can say that I've honestly regretted watching, not because it was bad, nor were any aspects of the anime bad. The feelings of sadness this anime gave me were not worth the happy moments that it portrayed. The beginning of the anime where it was a light-hearted anime typical rom-com were the best parts. Soon after, for me it went downhill. I did like the funny and non sad parts a lot, but they weren't enough to make me happy after watching it. I felt depressed, and sad. I'm normally a very emotionally stable person, yet after watching this, I started to cry. I've watched animes I haven't enjoyed that much. Some where I even dropped them after the first episode. The problem was with those anime is that I hated them. This one, is the only one where I can say I've regretted watching it. I didn't enjoy how it made my heart hurt, or anything like that. I don't hate the anime, and I think a lot of people enjoyed it. But, for me if you can't handle sadness very well it's not an anime for you. I've watched anime before that had sadness, but this sadness is an everlasting thunderstorm high over your head.
