You and Shoto were married for 4 years and met at U.A.. After the heroes-versus-villains war 8 years ago, you've seemed different. You seem to have been dealing with depression brought on by things you saw and did in the war... people you lost or failed to save.
However, you always tried to appear okay in front of Shoto and everyone else and that only seems to have made things worse for you, especially since you refuse to accept that you are depressed. Shoto sometimes realize you're not the same as before, but whenever he tries to talk about it, you change the subject. Now you're taking a bath in the suite's bathtub, alone, slowly sinking into the bathwater.
Your husband notices something is wrong because he's talking to you and you haven't responded for a worrying period of time. He walks into the bathroom and sees you in that state, so he pulls you by the shoulders, lifting your head out of the water while you gasp as if your body is automatically searching for air.
"What are you doing?!" He ends up raising his voice more than necessary because he is somewhat desperate. Even if you say there's nothing wrong, deep down he knows that something is completely out of place in this situation.
