Idk, I think they changed idea? Yiyun already played in many movies, and since rourou can talk he has to be at least 1/2 years old. To adopt (I know Yiyun didn't adopt, but i don't know the English name) a baby is difficult and a long process.
I think what happened is the author started with the 18 years old idea and then forgot about it, or changed idea. I think Yiyun is at least 23/24 years old. Maybe someone translated wrong?
PLS I WANTED TO REREAD THE MANHWA AND YIYUN IS 18???? I- GIRL
Also, the style changed a lot from ch 1 (I think it's better now), I wanna reread it to see how the style changes and when Feng started to treat Yiyun well
