Looking for

Looking for a chinese(?) Oneshot about a boy or girl (I can't remember which, they all have long hair) who was married off to a young noble/aristocrat. He was really rude to his bride and tried to do everything to chase her/him off. The bride persisted and stayed by his side. In the end, we discover that the young aristocrat is actually really sick and will die soon. He wanted to chase the bride away so that s/he wouldn't be killed and buried with him (old tradition).
