A girl, the contrast is great, what's the matter?

when you first met, she didn't know you at all, and naturally she wouldn't show her true self. She was naturally conservative in speaking and didn't talk much.

this does not mean that she is lying to you, but on the contrary, it means that she cares about your association.

Later, when she received your gift, she was very happy, relaxed her formality towards you and showed a cheerful side.

in addition, text messages are different from phone calls. Sometimes, what you can't say on the phone can be easily said in short messages. Because SMS is not a face-to-face communication, there is a lot of room for personal thinking.

since you have heard from your friends that she is cheerful, it shows that this is her true character.
