School Rumble, Asu no Yoichi! Recommendations
The relationships between a lot of the characters in these animes are very, very similar. As an example: you have the delinquent who softens up and is too shy to admit his feelings for a girl, while that girl happens to be in love with another guy. Both animes also includes a big amount of comedy, lots of love triangles and people wanting to confess their feelings.
Love triangles, people scared to confess, and people ignorant of people's feelings are main points in both shows. Asu no Yoichi is a little more ecch, i but nothing too extreme.
In both series, a delinquent character softens up and changes upon falling in love with a female character that is in love with a different guy. Both of these male characters desperately want to confess their feelings for the female character but different people and events keep getting in the way
