The constant blushing is rather adorable.
@jRyder96 - What's there to avoid for Akiko? She scarred by what went on in her family around Christmas time, but she has no connection to her dead sibling, no memories. It would probably be best for her if something good happened to her around this time to replace the background doom&gloom with a happy memory.
As for emotions breaking out, I think it's the Japanese way, at least traditionally, to not allow that to happen.
Better jump off a bridge instead of "burdening" someone.
