Huo Sichen couldn't be bothered to explain.
If Li Susu were a money-obsessed woman, she wouldn't have stubbornly pursued him with all sorts of methods when he was still a doctor.
Back then, Li Susu was certainly thick-skinned.
When he worked the day shift, she would fake illness daily and queue up. Sometimes she would wait for him for hours, still cheerfully greeting him but unable to articulate her discomfort.
Eventually, Huo Sichen threw her out.
When he worked the night shift, she would wait by his car. He remembered a few times when he had to perform emergency surgery for patients and didn't leave the hospital until the early hours of the morning.
When he was ready to go home, although Li Susu was clearly so weary her eyes couldn't stay open, she would still hop out excitedly to greet him.
If it wasn't for the incessant pestering by Li Susu and her unpredictable nature, bouncing out late at night when he was weary, she could've faced some serious danger several times over.
