After the death of her second aunt, Guo Qi was dragged back to Tandufang, where she once again met the "little fat man" from her childhood.
Guan Yaqing didn't expect that she could be disturbed when she was peeking ("hiding") at someone, so she responded by "twisting her ears" to retaliate against "Little Qiqi".
Guan Yaqing: a first-year graduate student
Guo Qi: Sophomore "new" student
So... The female protagonist is three years older than the male protagonist (female is a junior, holding a gold brick?)
Purpose: Be loyal to yourself before being loyal to others
