Yeah its honestly kinda wild to me that people have these expectations for Xiao Lu, especially considering the earlier chapter specifically showed us how she has this entire high-effort het disguise just so people dont get suspicious.
Not to mention that, although TongTong has obviously turned out to be a sweet and kind person, shed be confessing to someone who initially "blackmailed" her.
I get it, honestly. It's easy to read this comic from another country, full of characters that anybody can relate to, and think "Why wouldn't these characters do what I would do?" without considering that the cultural situations are different. Kids (and young adults) in the US are pretty lucky that homophobia and sexual discrimination aren't widely accepted among their generation. It's a privilege we enjoy, it's easy to miss that people in other countries have to fear that being an out homosexual could destroy their lives.
