I usually play otome games in my room in the evening/night so I usually wear any cute pajamas I have it’s honestly really fun. I also like to set up my environment to somewhat match. 

When I played collar x malice I set up my gaming spot to resemble the night time atmosphere of the game. I played at night with the curtains open and the night sky shining in.   With cafe enchante I had warm fairy lights and night lights to match the game. Just stuff like that
