Stella didn't care. She had to tell the truth first!
Although the man's chance of returning to the RK mansion was very low, he couldn't come back once a week. When she had just moved in, the man could stay away from home for two or three months. That made Stella realize that RK was a man who hadn't returned home for many years...
It wasn't bad for her to live alone in the RK mansion.
At least, she didn't have to face that man's cold face all day long.
Over time, Stella got used to it.
What's more, When she was in college, she rarely went back to the RK mansion, so Stella didn't think much of it.
Occasionally, when she went home on the weekends, she still... didn't see the president come back.
