Qingran and Xie Ying'an aren't completely out of touch; they squabble but it hasn't escalated to a full cold war where neither talks to the other.
Right after Tang Xiaoxue asked her which department's heartthrob between the Physics Department and the Math Department looked better, before Qingran could answer, Xie Ying'an's call came through.
She hesitated for a moment, then slid to answer the call, whispering a soft "Hello?"
The other three roommates, adhering to the rationale of not disturbing others on the phone, stopped arguing about who was the most attractive.
The other end was very quiet, not sure if Xie Ying'an was outside the dorm, he asked: "Haven't gone to sleep yet?"
His voice sounded a bit stifled.
Qingran moved the phone away slightly and glanced at the time on her phone, it wasn't even ten yet, who goes to bed that early?
"No."
Xie Ying'an was silent for a while, then asked: "Are you free tomorrow?"
Tomorrow was the weekend.
