If you liked the Toradora! anime, the Anime-Planet community thinks you'd like:
Maiku Kamishiro has always had a photo of himself as a child in front of an old house with a young girl. One day after spotting the building in a news report, the high school boy moves to the countryside to live in the house from the picture. While living alone, making ends meet by working as a freelance programmer, Maiku gets the shock of his life when not one, but two girls turn up on his doorstep claiming to be his twin sister! With the lively Miina and timid Karen both possessing the same photograph, the pair begins living with the confused Maiku as they try to figure out which one of them is actually his sister.
Not only are the character designs similar, some almost look identical, but also the way it makes you feel and gets you to cheer for both people involved. Even though you know only one can get the guy in the end.
Mei Tachibana has had neither a friend nor a boyfriend in 16 years, and she doesn’t plan on ending that streak any time soon. The outcast learned years ago that social obligations only lead to pain, and has carefully guarded her heart to keep from getting hurt. However, the girl can’t stay withdrawn forever, especially after attracting the attention of the handsome Yamato, who finds her caustic personality interesting and strives to date her after she roundhouse kicks him down the stairs. But even the most earnest of romances can be crippled by jealousy and insecurity, and this pair has plenty of both. Can their feelings for each other overcome their own emotional weaknesses, or will this love perish before it even begins?
Both of these series will take you on an emotional roller coaster. I haven't quite finished Suki-tte Ii na yo (Say I love you) yet, but so far I've absolutely loved it. It's about a real girl with real insecurities, dealing with her first love.
Toradora! is also a coming-of-age high school romance, albeit with quite a bit more comedy and laughter. Tears of joy flowed more plentifully than tears of sadness, thankfully.
Yamato Akitsuki has recently moved to Tokyo, and in order to maintain his less than wealthy lifestyle, he currently works at his aunt's bathhouse. While walking by the school one evening he sees a girl by the name of Suzuka practicing the high jump, and is instantly in love. Even better is the realization that Suzuka lives next door! Determined to prove himself worthy of her affections, Yamato decides to join the school's track team and show her what he’s got, but things won’t be so easy; for Suzuka has a love interest of her own, and it isn’t Yamato...
Both are Highschool Romance Comedy-Dramas involving a male character deciding between a tsundere and another girl. While both try and deconstruct the classic tsundere character-type, Yamato in Suzuka is able to remain front and center of the story in his relationships, while Ryuji in Toradora! is quickly pushed back to center on the Taiga's struggles and her relationship with Ryuji. If you enjoy the mood whiplash of one of these series, you'll enjoy it in the other.
After being turned down by his unrequited crush, Hachiman Hikigaya is determined to live out the rest of his high school life single and socially tuned out to avoid the folly of youth. But Hachiman's resolve is lacking compared to his guidance counselor, a woman determined to change the boy's ways. So, much to his dismay, Hachiman is soon forced to reach out to those around him by joining a club dedicated to serving others. Alongside the cold, but beautiful club president Yukino, eager Yui, and other new friends, Hachiman will try to stomach his new volunteer work and survive his ultimate fear: being involved in a typical high school romantic comedy.
