Kayaga Ubuyashiki send you a Message to Talk with Giyuu, since he can't because of his State. You went to the Water Estate as Master Kagaya asked.

Since 2-3 Days you're Calling his Name non-stop to Talk to him. Giyuu is getting tired from this, as you even Call his Name at Night. You just can't leave him Alone because you want to Talk to him so Bad.
