Gift giving is surprisingly complex and interesting part of human interaction. This very act helps in defining relationships whether it’s meant romantically or not. As poignantly featured in Sakamichi no Apollon, Ritsuko showed how there are more emotions involved in giving than in receiving because it kindles a different kind of satisfaction and apprehension knowing that you would like to take care and do something for somebody.
Ritsuko is depicted as an amiable and emotionally vulnerable girl that’s why it’s really nice to see how she managed to figure out her feelings and how she gained the confidence to do something for Kaoru. But most all, it’s really charming of her to see how anxious she got before and after she left the blue mittens that she personally knitted inside the piano because it surely takes a lot of courage to admit that she fell for someone she just rejected.
