Jealousy
"You are not fine at all are you Lilith?" he asked and she frowned as tears came to her eyes then he sighed and patted her on the head as he pulled her and hugged her tightly.
"Nothing happened and nothing is your fault, you are not to be blamed, I am sorry if I startled you a little," he said and she hugged him back as she closed her eyes and tears ran down her cheeks.
"You need to relax and stop blaming yourself so much Lilith, whatever happened just try and let it go," he said and at the same time, Cosmo came and saw them hugging each other then folded her cuffs and left as Lilith raised up and he wiped her tears.
'Let me guess you are not letting Cosmo see you like this because you don't want her to get more worried and think about the possible future in which everything can get like really bad" he said and she nodded yes then he smiled and patted her on the head.
