Karin doesn't want her relationship with Toshiro to be like the relationships the girls in her class want to have, or even what her sister expects her to have. She knows Toshiro well enough that their relationship will always be different, and she is fine with that. Disclaimer - I don't own Bleach. Note - The custom in Japan for Valentine's Day is for the girls to give chocolates rather then the guys giving gifts. Chocolate given to a guy you like is called "honemi-choco" and chocolate given to a guy friend or a co-worker is called "honemi-choco". Chocolate given to a female friend is called "tomo-choco". A month later the guys reciprocate the "honemi-choco" by giving the gifts on what is known as White Day. Amanatto is a type of Japanese candy made by covering dried beans with sugar - this treat happens to be Toshiro's favorite food.
