"There is a bulletin board in the sun room that you can use to post messages. It's in the lounge you've walked through on your way here," Seishin explained, "It's useful, but the staff will be able to read your messages as well, so you should exercise a little caution."

Indeed, the bulletin board would be a good place to start if you were searching for something. Seishin didn't know what sort of items Link-san had before arriving here, but they must have been important.
