Tangerine.

After going to get the tangerines from his residence, he indeed escorts WooPil back to Zhongli's residence. He realises that their father is probably back, but he accompanies the little brother inside nonetheless, so that he too can say hello to dad.

He walks inside and puts WooPil, who is holding two tangerines in his hands while Chan carries the whole bag, down. «Dad?» He ventures further inside, followed closely by WooPil.
