Lin Mo goes into a different world every night when he sleeps. Sometimes it's the prince guarding the city, sometimes it's the border guard watching the stars, sometimes it's the old fisherman casting the net. When he wakes up, the most unique ability in that world will be condensed into a small thing, and he will put it into a glass cabinet that appears out of thin air on the third floor of the library.
He originally just wanted to be a handsome college student who was messing around, until one day the souvenirs in the cabinet began to resonate with each other, until he found that every time he looked up at the stars, he felt like crying for no reason, until--
He discovered that rows of dents that were not of this world began to appear on the wall of the storage room.
The shape of those indentations was perfect for all his souvenirs.
