I sent a message asking the girl if I was romantic, and I replied with an expression.

Responding to a smiling face usually means being shy or not knowing what to say.

Girls are generally more introverted, so if they are shy and can't say "I'm a little shy" directly, they will cover their faces. For example, if you say you want to invite her to dinner the next day, she will say yes in her heart, but to show reserve and shyness, you can make this expression.

In the second case, the chat is dead, so that girls don't know how to answer the words, and you will also cover your face, indicating that you are speechless. For example, if you show off your story to girls, girls find it inconvenient to express their opinions. At this time, you can usually turn the chat into a normal track by changing the topic.
