This is a pretty heartbreaking story but at the same time quite healing, I truly loved it and it´s the kind of thing I´d definitely read again. Even if it´s a short manga, I found it easy to connect with the characters. I just wish it was longer because I´d love to know more about Tsukasa and I think the conflict that took him to want to die should´ve had more space to develop; and also because I kinda like heartbreaking stories and seemingly I wanted to suffer for longer.
