How to express your feelings without embarrassment?

Confession should be vague, not too abrupt.

You can't confess to that girl when she doesn't know you or you don't know her well, which is easy to fail, because girls don't know you or even know you, and girls generally don't accept confessions from strange boys, so the probability of your confession success is almost zero, which will also put you both in an awkward position.

In order to avoid this embarrassing situation, you should first establish a good communication relationship with a girl, and then you want to confess. Let her know you, at least know her. When she knows you to a certain extent, you can think about how to express yourself, so that girls will not be in an awkward position because they are strangers.
