GUYS ! If you found out a girl liked you indirectly ...?

Well, you need to find out if he's going to anything in the near future. Then you can show up and have an excuse to talk to him. If he's not going to anything soon, maybe you could arrange to meet up with your friend who could also invite him. That way, it's just you, your friend and him. You'll easily be able to talk to him then :)
