Ah, that's right. He Jichen is Lin Ya's boyfriend. They bumped into each other at the same hotel—it's only normal that they stay together at night...
But... this didn't seem like any of her business. She didn't need to think too much about the two of them; she was just there to drop off something for Lin Ya. The sooner she dropped it off, the sooner she could leave. Most importantly, she got so upset with He Jichen just two hours ago in the corridor of the restaurant that she didn't want to see him. Since he was now in the bathroom, she could use this chance to drop the stuff off and disappear...
With that thought, Ji Yi quickly snapped back to her senses and hastily walked into the room, carrying the shopping bags.
With the doors shut, Ji Yi didn't see Lin Ya in the living room, so she assumed Lin Ya was in the bedroom.
