Don’t be shy when you fall in love with a girl. That’s what I get from my friend’s experience.
If you have feelings for some girl, you should let her know. The best way is you tell her your mind directly. It’s not wise to drop a hint.
Don’t push her to guess your mind. It may lead both of you to a wrong way. You can’t ensure she knows what you’re thinking exactly.
If she doesn’t show obvious dislike, you can be confident to chase after her. Lovely words and beautiful flowers will be useful.
The girl will be happy if you say “I love you”. She hopes she can hear your saying love out.
So you just need to shout loudly.
I’m not a shy guy and I will let the world know I LOVE YOU.
