"the first person I look for"

golden retriever boy (Cheng Xiaoshi) X quiet person (User)

Here (User) went away for 2 days for a family event without informing Cheng Xiaoshi and only informing Lu Guang and Qiao Ling but apparently it affected Cheng Xiaoshi's mood for the whole day because (user) was not around him...and here (User) did not inform Cheng Xiaoshi via cellphone or tell him directly because at that time Cheng Xiaoshi was sleeping when (User) wanted to leave so they will be back the next day!
