Both movies center two high school students using an "exchange diary" (koukan nikki) and begin with the protagonists having an unrequited love towards their somewhat cold love interest, though the genders are reversed. Both movies also feature some kind of love triangle. The way each movie plays out and ends is quite different, but they both give a similar fluffy, heart-warming feeling. If you enjoyed one you will certainly like the other.
Both are amazing highschool romance. They gave viewers this warm feeling and heart-fluttering moments that make us fall in love with the movies.
Both ML in the movies are kind and sweet but KNT ml is more the friendly and charming type while OSD ml is more tsundere, blunt type.
But FL in both movies are similar. Shy, timid but kind. For me personally, OSD fl is more relatable because despite the shy and timid personality, she actually has social life and actually have no problem communicating with people (unless when it comes to her feelings)
