Its harder to admit you're gay to your own family than a random stranger in street or forum cafe
I get it why he didnt want to said it since the fact that Jiho also knew Youngji feelings to him... Its gonna be hella awkward..
Imagine being in their position..
Jiho gonna drop his jaw if he knew lol
The guy who used to had kinda of a fling with his bf now dating with his bf ex-crush
Jiho is gay. At the very least Eunho knew that Jiho doesn't mind gays. So this is not a matter of coming out or not. Besides Eunho just keep saying about "personal life" not about coming out. And Jiho respect his brother so much. It's just feels missing okay. As I said no matter what family will know it sooner or later. Even a lie will come out too. So that's not the reason.
What's wrong with surprised? They probably jaw dropping at each other pairs and then laugh it out loud. And they gonna have fun doing double date.
But honestly I don't like how the Eunho doesn't want to talk about whom he was dating. I mean... Personal life? It's his own brother. No matter how much they hide, eventually, at least, Jiho will know about it. So well, I'm a bit dissatisfied because in the end the don't tell each other about their new boyfriend. Only Youngji who knows all of it. Feels missing. And besides the damn title says "No secret". Isn't this suited to be title "Secret between us". Well it's good to pass time.
