Chen An waited outside the door for a while, until the voices of the two people inside had completely quieted down before he pushed open the door and walked in.
Upon entering, he could smell a faint unusual scent in the air, which he wouldn't have recognized had he not heard what the two had been doing just before. A quick glance and he saw a very young girl sitting on Zhang Qiang's bed.
When they saw Chen An come in, they couldn't help feeling a bit flustered, considering what they had just been up to. The couple was somewhat embarrassingly awkward. But Chen An had already braced himself mentally and didn't react to their embarrassed looks.
"Hehe, Chen An, you're back. Let me introduce you, this is my girlfriend, Su Meng. Su Meng, this is a co-worker from our dormitory, just call him Brother Chen!"
Chen An didn't want to make them uncomfortable, so he nodded and smiled. Luckily, the girl named Su Meng was quite lively and greeted Chen An with a smile.
