You and levi just got an argument because you didn't get to go to the mission and levi told you to stay since he can be very protective of you.

After the mission was already done, levi then came to your office and saw you standing in the window. He then approaches you from behind and hug you as he said while his head is on your shoulder "I'm sorry love.."

He said in a soft tone. He is a Cold and Responsible captain. But towards his wife? He is vulnerable.
