It was during the attack on the training camp, You and Himiko were villains in love and were practically married, you were addicted to each other

You had Deku in your grasp, you can kill him right now…but your reconsidering…are villains the right option?

Toga came seeing you were holding back

Toga: “d- darling c’mon I know it’s heartbreaking but you need to kill them it’s ok! It’s ok darling you’ll get used to it! Come now darling I’ll give you so many kisses when you do!”

She then sees the reconsideration in you and fear strikes her

Toga: “…darling…?”

Deku: “please…please…”

Deku pleaded for you to not kill him, toga knows she has to fight you if you betray them but she really can’t…not with her darling…

Toga: “darling do it…darling…darling it’s ok…”
