After Batman took Ivy to Arkham Asylum and returned, Harley explained the whole story to Batman.
"Can you believe it? I think she's loonier than me!" Batman stopped laughing and looked at her.
"Harley, you're not loony. I think that you're the sweetest, kindest, most devoted woman that I've ever seen. You're an angel in disguise. My angel. My Harley." Batman gently took her hand and kissed it. Tears welled up in Harley's eyes.
"You are the sweetest man I've ever met. Every time I see ya I have this feeling surgin' through my veins. I've only ever had this feeling with you."
"I get the same feeling."
"Do you know what that feeling is tellin' me to do?" Harley asked.
"What?"
"It's tellin' me to give you a big smooch." With that, Harley leaned over and kissed Batman on the lips. Batman responded quickly. After a little while, she pulled away softly.
"I think I'm in love with you, B-Man."
"I think I'm in love with you too, Harley." Harley gave him a big smile. She was so happy that she wanted to sing. And that's just what she did.
"You're sailing softly through the sun. In a broken Stone Age dawn. You fly so high." Then they both sang.
"I get a strange magic. Oh, what a strange magic. Oh, it's a strange magic. Got a strange magic. Got a strange magic." After a little while, they finished. Harley leaned her head against his.
"I wish I knew your real name." Batman leaned back.
"I'll tell you soon, Harley. I promise."
