I've read my fair share of manga/manhwa but I rarely get THIS level of reality.
Usually in anime/manga, they talk about seniors as nothing more than just a step in everyone's lives but here it's taking such a more personal role and turn. Young adults and teenagers can relate so much to whatever the characters are thinking. These emotions are universal and having a representation of those exact feelings and heartsinking questions in a physical media can make such a big difference in a young person's life!
One of the greatest SOL stories of the decade...maybe even of the century!
