For Your Sake, I’ll Never Leave Your Side

The two haven’t done anything yet—their true selves are naive, they are innocent, and they have never thought about something like falling in love, even in a dream. On that day, the delicate, young girl working in the bento shop meets... This is the story about a boy and a girl who, innocent and with no experience in romance, suddenly begins their lives as newlyweds.
