"Liam what is love?" Null asked after the day and they were both ready to turn in for the night.
Liam knows Null wouldn't ask him such a question unless he's heard it from someone. "Who told you about it?" he said.
"Vera, she says you loved me," Null replied. "Water was coming out of her eyes as well," he said. "What's crying?" he said, remembering he also had a question about that.
"Love is a complicated emotion," Liam said, he isn't sure if he loves Null as Vera says, sure he loves spending time with him, and would do anything to keep him by his side, and he would probably do anything for him.
His face slowly began to heat up. "Good night," he said then left to his room, leaving Null a bit confused.
"Is he sick?" he muttered. "Maybe I should go and check the internet."

The next day...
Null spent a lot of time researching not just love, but also the concept of emotions and it wasn't very clear, but he understood it.
