See the dialogue between Haiping and Haizao about marriage in Episode 32 of Small House

Guo Haizao: Actually, I still like him a little bit. Being with him is quite exciting.

Guo Haiping: Exciting? What excitement? The excitement of having an affair? People, you only dare to squander your youth like this when you are young. When you reach my age, you will know that under the premise of having an honest husband, obedient children, and a stable residence, sex is What a blessing it is to be in your own bed instead of in someone else's bed, worrying about being caught at any time. ——"Small House"

Yes, when I was your age, I had a lot of youth to waste. As for me, I followed the normal life path, graduated, got married, and had children. I lived meticulously. Live a cautious life. To be honest, I am not qualified to teach you a lesson, because I have never walked the path you are on. It's hard to say, in today's society it's really hard to say which choice is right and which choice is wrong. Whose way is it? Let him walk it himself. Whether you are tired or not, good or bad, worthwhile or not, others cannot answer for you. So, I am not advising you, I just hope that you, don't be fooled by all superficial phenomena, including your relationship with Xiaobei, including your relationship with this Song. Think it through quietly when you are alone. Once you think it through, you'll know what to do. Okay? ——"Snail House" Guo Haiping
