Sweets.

The next evening from their arrival in Heinmenhos he goes out for a walk in the city, because he really needs some time by himself and something to distract him from the haunting thoughts about LianBi being in terrible danger.

While walking in the dark, by closed stores, most of which that will not open until the war will be over, he comes across one with wide open door, but all lights off. Did the owner forget to close the door? He shrugs and naturally walks inside. LiMu makes him even more curious than Sha and his influence is stronger than that of the other Guardians.
It's a candy shop, with whole barrels full of sweets of all tastes, shapes and types, other than colours.
He walks among the barrels, a little hesitant, just touching the candies with the tips of his fingers until he decides to take a few. He has never, ever eaten a candy so far. Not because he never had the chance to, when in Seoul, just because he was always too prideful to give others the satisfaction to know he followed their advice to try them. #wenchthings
He tries a few, then devours a ton.
In the end, he grabs a huge barrel of his favourite ones and carries it back to Jackil's manor, putting it in the basement of the house, which is also where he spends most of his time anyway.

He sits on a wooden box right next to the barrel and starts to eat a few candies, which look like blue crystalline spheres with a delicious liquid inside.
