I think, just so-so, 1. Just like a relatively introverted little lady, if she is embarrassed to speak, she will hint at you in some ways and try to catch something hidden. You should pay attention to this. What does this song mean after something like "I can't tell if you are a friendship or a missed love"? You should know ~ I suspect that she listened to this song for you, not just for sharing, because this song is no longer a new one! But you'd better not be too impulsive and recall the scene at that time.
If you like her and you find that she likes you, then you should try your best to let her know how much you like her and care about her, such as giving her something one day.
3. Every girl likes a gentle and considerate boy, but gentle and funny!
4. "I can't tell whether you are friendship or missed love.
I'll give you a trick. You pick some dandelions for her, pack them in a flower shop, take her to a big lawn, play this song, send her flowers, and recite emotionally "I can't tell whether you are friendship or missed love". She promised that she would be moved to death! At this time, you are putting your hand on her shoulder and trying to hug her a little. Don't worry too much (this plan can only be implemented after you are sure that she likes you and wants to be with you) or she will hate you.
Well, bless you ~!
