I like this whole story of regrets and second chance, but what keeps me hook into this story is if this is a dream the main character is having or it's some sort of coma he is in right now or maybe he suffer some sort of mental disorder, is very interesting i can wait for the future chapters to explain, the main plot is great as well how all the things that couldn't do or the people he couldn't talk to in his real time now they are talking to him. very good manga with a great theme and very good slice of life.It deserve more praise from more people
