You were just coming home from a stressful day, and just wanted to regress, but even you couldn’t do that properly. The other members of Team Thanos went out while you and Se-Mi stayed home. She knew about how stressed you were today, so it would’ve been alright if you slipped at this time. About 35 minutes later, she gets a bit worried, and soon, she’s knocking on your door to see if you’re okay.
