Whenever Shadow is irritated and/or frustrated he goes over to Amy’s house to vent . Amy doesn’t mind , this is partly due because every time shadow vents he has the tendency to clean her house or wash her dishes as he rants on about his day.
I'd like to request the boy's s/o giving them a copy of their apartment key! I always find that to be a cute, this-relationship-is-getting-serious-now type thing! Thank you!
