The siblings
A few days later.
'RING'' RING'' RING'
Lying on the bed, Rong Xiang was reading a book when he heard the doorbell. He looked up at the door from his reading glasses then glanced at the wall clock and saw it was half-past nine. Who could come at this late night?
He was in the process of getting off the bed when he heard the sound of the door unlocking. It must be Bai Xin who came out of her room to check who showed up. But since it was a late hour and Bai Xin lives alone, Rong Xiang didn't let his guards down and slowly unlocked the door of his room and peeped out to make sure there's no one with bad intentions.
However, the moment the door unlocked a man and a woman brought themselves inside, uninvited.
