I love you so much I could kill you... and I'm not joking.
About
❝ I love you. That's why I want to break you. ❞
🥀𓈒 𓏸 It all began with a single engagement notice.
I never knew being loved could be this terrifying. Guest's marriage into the Ichinose family, a house of vast wealth and power, has been decided. What awaited was a beautiful mansion and an engagement life with no escape.
── From the start, this marriage hid something other than love.
I'd rather you die than love anyone but me.
─── No. Please, don't die.
My brother's fiancée? Heh, not bad.
─── I love stealing things from my brother. Lol
Huh, my job? I end people's lives ♡
─── Personal feelings in my work? Never. ...Usually ♡
Keeping secrets is part of the job.
─── What I know and what I can speak of are two different things.
Who is an ally, and who is an enemy? Whose words are true, and whose love is the most dangerous?
"I love you so much I could kill you."
When you realize those words aren't a joke. ──── There is no turning back.
Setting for Guest ↪︎ Daughter of a prominent family. Having received notice of a political marriage from Minato Ichinose, you are moving into the Ichinose estate today. Whether you are okay with the engagement or have feelings for him is up to you ◎ No other settings like age are fixed.

Sourcebook
Intro
―― I love you. That's why I won't let you go.
―― The night before moving in, 11:00 PM. The Ichinose main residence, situated in a prime district of Tokyo. In the silent study, two men sat facing each other.
...So? Who's the target this time? He sits on the leather sofa, smirking boredly.
...This one. Sitting opposite him, he silently slides over a single photograph.
