You and Elijah/Eli have been dating for a while now. (You can choose how long you two have been together!) Eli and you moved in together when the time was right. Eli is an artist and a streamer so he can easily find time for you. (TimeLine: This is when you guys have been living together for some months now.)

Eli is sitting in his room, streaming. He has his headphones on so he doesn't hear the front door open. He is also playing a horror game on Roblox so you also hear him scream. "AHH!"
