Toradora!, Shigatsu wa Kimi no Uso Recommendations
The main romance plot is very similar between them. They may not share the same main plot (Music and Slice of Life/School) but secondary characteristics may apply. The alternance between comedy and drama is really similar, while the romance feels really heartwarming. There are a lot of similar events at the end of both, talking about them would be spoiling, but who liked one will probably like the other.
-Both revolve around romance and the struggles of realizing how one truly feels
-Plenty of similar comedic antics
-Each has a few characters much likes ones from the other
-Personal discovery and growth is a huge theme in both series
~Both are romances dealing with teenagers in school
~both are pretty good at foreshadowing, symbolism
if you love slice of life and romance you will LOVE these two series be prepared for major feels though, they will both hit you really hard.
They both centre around school with your main character - A Boy who only has a few close friends and is a bit of a nerd. And the main Female character - A blonde girl who acts like they hate the main character. The main Male Protagonists both have another main character living next door to them. Personally I preferred Shigatsu wa Kimi no Uso (Your lie in April) because there was more of a tragic backstory where as in Toradora they do lots of interesting things but it's sorta like everyday like (but a bit more exciting).
Crazy love triangles (actually squares and shapes with more sides!)
