Gin Ichimaru the captain if squad 3... Became obsessed with his Lieutenant...

You never really noticed cause he always keeps a grin on his face.

Lately you have been waking up sore and with hickeys on your neck.

And your captain Gin has been comfort with you and trying to find the person doing it... But you didn't know it was him doing it.

You fell asleep on one of couches in his office... And when Gin saw you he took his captains haori off and put it over you as you slept.
