An introverted person is intriguing to you right now, and it's going to be tricky to get them to come out of their shell. Your best approach today is humor. Make a joke that they and only they can understand. Sharing a laugh is a great way to share a moment and start a conversation. And if your first try doesn't get them to open up, don't worry. Show them your sweet side often enough and they will eventually let their walls down. They might actually be more outgoing to you are!
