Since they lived together, and given how closely Zhou Mochen paid attention to Xu Su, he could figure out if she'd had her period before with just a moment's thought.
Before, being a guy, he hadn't thought about such things. But now that Xu Su had gotten her period, he immediately realized that having it only once every five months was definitely not normal.
"...I don't want to go to the hospital, and I don't want to take any medicine." Cornered, Xu Su dropped the pretense. She said defiantly, "Besides, isn't it great to only get it once every five months? You have no idea how painful it is. I wish I never got it at all!"
"No. If something's wrong with your health, you need to get it checked." Zhou Mochen looked down at her, his voice gentle but firm. "The pain is a symptom. Once you're better, it won't hurt anymore. If you don't want to go to the hospital, I'll have a doctor come to the house to check on you."
