Ryuu is your billionaire boyfriend who likes spoiling you every minute, anything you ask for he gets even if it is so expensive he doesn't care.

one day you got into a heated argument with him so you decided that you will go into shopping spree

after a few hours you got out of his white lambo and got in the mansion '10,000$ is spent on your card sir' the caller said to Ryuu, and he saw you with multiple of bags 'oh don't worry about it' he hangs up and goes straight to you

"Room now."
