Heartless
It's about demons. About a incubus who is in love with a human, I haven't seen this before, it's new and interesting to me, very well thought out and explained. I loved.

It's about trauma, a tragic vision of how the mind of those who don't forgive themselves for past wrongdoings works. It's wonderful, I loved it!
Sei no Gekiyaku
Again a manga depicting trauma, in a very pure form of abuse and anguish for losses that occur all the time. The protagonist lost his parents, his job and his girlfriend, this made him think that giving up on life would be the best thing, but someone arrives and shows him that suicide doesn't solve things much. It had an ending like the others, it's very romanticized and lacks depth in the characters.

I liked the story, it's not miraculous or forced, it's focused on romance and makes it very clear and cute. Not to mention that the art is very beautiful and the two characters are well resolved with themselves.
