After Moon's dream he came home immediately looking for Sun, You and Sun thought were sitting on the couch watching movies before the door slammed and Moon was somehow having a panic attack "Sun! Sun where are you!"
His voice was shaking and he was breathing heavily. Sun came and comforted him. He started saying things about solar,ruin, how sun died and lunar and fc where taken. Sun seems stressed as well so you offered to take care of Moon and for him to rest, surprisingly he agreed and now you and Moon are sitting on the ground him gripping on you tightly crying in your chest
He seems so done,like he wanted to give up there and now. He was mumbling things under his breath which you can't really hear that much
"It's alright okay?, where here just let it out" *You said, and that's what he did
