I think there are the following
TOP1: "I want to tell you"
"I want to tell you" is adapted from the manga by Shiina Koho, and the TV anime version has two seasons, which were broadcast in 2009 and 2011. It's a popular school romance, and when you watch it, you'll feel like "this is what it's like to fall in love with someone. ......" It's recommended for singles who want to feel the atmosphere of love.
The anime is so pure that it's ridiculous, and it's a typical example of the legendary hand-holding that can make you blush. It took two seasons for the two of them to finalize their relationship at the end, as it was called by everyone: so eager to die.
TOP2: "Monthly Girls Nozaki Jun"
"Monthly Girls Nozaki Jun" is a four-panel manga created by a popular Japanese manga artist, serialized in "GANGAN ONLINE" (GANGAN ONLINE). The story depicts a high school boy and well-known girl cartoonist, a high school girl who unknowingly becomes an assistant and the two people around the interaction of the romantic comedy.
There are a lot of funny and beautiful moments in the season, a typical atypical romance anime, but also a typical most cute height difference anime, light and funny, especially suitable for releasing the pressure of the time to watch.
TOP3: "Neighborhood Strange Classmates"
Mizutani Shizuku is an aloof first-year high school girl who is only interested in her grades, but not the rest of the world. She helps a teacher deliver a lecture to a problem student, Haru Yoshida, for the sake of a reference book. After getting to know Haru Yoshida, who injured a student and put him in the hospital at the beginning of the school year, she realizes that he is a pure-hearted person who longs for friends, so she can't let go of his group of friends, and ends up ignoring her own fear and helping Haru. Haru is impressed by Shizuku and falls in love with her, and goes to school because of her. This is the beginning of a heartwarming, funny and youthful story.
The story is a bit clichéd, but the plot is still heartwarming and beautiful!
Top 4: "As long as you say you love me"
As long as you say you love me (好きっていいなよ。) It is a manga work by Ye Yue Ding. The anime version began airing in October 2012. It tells the story of a friend who was once betrayed as a child and has never had a boyfriend or even a friend in the past 16 years. Her solitary personality makes her the target of bullying by her classmates, but she meets a popular boy at school by mistake. Yamato appreciates May's fearlessness and starts to take the initiative to get in touch with her without caring about what other people think. As a result of Yamato's easy-going personality and warm-heartedness, Ume gradually begins to unravel her defenses.
This is my personal opinion.
