Girls ask me who I like, and I say you. Is this a confession?

The girl asks who you like, your answer or him. Of course, it's a confession. It's not too formal, but it has shown your attitude.

So this time, this girl should have understood your heart. Now that you have finished talking to him indirectly, find a more suitable opportunity to formally confess to him next time, because we should respect each other.

After this happens, you should first tell the other person what you really think, and then take care of him and get in touch with him more in daily life. After a long time, he will think that you are a person who can be entrusted for life, and he will marry you.
