 If you liked Toradora! |  ...then you might like Boku Koi Conductor |
Both Boku Koi Conductor and Toradora! have a similar concept of "Boy helps girl to win her crush but falls in love with the girl instead". The main difference is that Boku Koi Conductor delivers it in a more comedic fashion whilst Toradora! delivers it in a more coherent and serious story. Just my 2 cents~
