1-gatsu ni wa Christmas

The protagonist, a calm and patient man, meets a childish, spoiled woman with a bad temper who creates a bad first impression on each other. Later he discovers that this lonely tsundere girl lives in a big house alone and neglects herself and the protagonist forms bonds with her wanting to help and take care of her.
Both are very similar, for me, Toradora could be inspired by 1-gatsu, or this is a very strong pattern of tsunderes
