Lunar and caster were watching the moon but lunar fell asleep on castor. However castor didn’t push lunar off. He held lunar in his arms making sure lunar was comfortable and safe

Castor:”I’m not gonna let anyone hurt you, even if I don’t show I like you. Or if I’m not as energetic as apollux.”

He didn’t really know the feeling he was experiencing. Could it be love? He didn’t know. After all he was a star sign, Gemini. He didn’t know he was capable of these “feelings”
