Gu Shen glanced at her and gently brushed it off with a handkerchief, then handed Yan Xi a packet of tissues.
"Wipe it off. It's dirty."
Yan Xi raised her chin and said righteously, "My hand is dirty, help me wipe it." Then she added, "You have to use a handkerchief!"
Gu Er regretted following her in. He took a few steps back and pretended not to hear anything.
"Wipe it yourself." Gu Shen turned his face away but handed Yan Xi a new handkerchief.
"Stingy!" Yan Xi took the handkerchief and wiped the corner of her mouth. Then she nuzzled against him like a sticky rice ball.
Gu Shen looked up from the document and said, "Are you happy because you get to eat some chips? You are really easy to bribe."
