BNHA Yandere BF Scenarios

Hi! Au Headcanons

So if you follow my tumblr you MAY know I give random ideas when I don't feel like writing full stuff atm. Some time ago, I made a certain post about combining my two favorite sources of angst :)

Hanahaki and a soulmate AU. I call it (obviously) Hanahaki Soulmate AU and the rules of it are simple and to the point.

1) You and your soulmate share a flower tattoo on some part of the body, traditionally the lower back but on occasion can be on other locations too which can indicate whether one or both of you are outside the 'norm'. This flower represents you two, but even the darkest of flower meanings do not mean you are toxic together, usually the flower is meant to show what you are to those who see you.
2) This flower is the same as your Hanahaki flowers or your partner's! The Hanahaki activates after the soulmate processes an action as rejection of the bond and love.
3) The way you fix this goes about the same way as normal Hanahaki BUT no surgery exists in this AU. The reason is there's no possible way to keep you alive without your flower and this can kill your soulmate who rejected you as well.
4) What motivation does the soulmate get if they have no idea ? Well, the soulmate will begin seeing ghosts of you in potential death images no matter where they turn and will even see these in their dreams and or nightmares. Once or if the Hanahaki is cured, your hanahaki flowers die and for a solid week, or if on meds, 3-5 days, you feel massive amounts of pain, as if your Lungs were having PMS.
5) if a soulmate dies, the tattoo will change to wilted flower. If your soulmate isn't born yet, it's a bud.
6) on occasion you can have more than one soulmate in a group. You can tell how many you have by looking at how many flowers are in the tattoo. If there's more than two, that means you have more soulmates.

And what better way to introduce my AU than to make Headcanons of it in my Yandere book?

Pick a character I have done thus far and I'll answer their headcanons using this outline:

- When would Yandere meet darling?
- What darling would be the best soulmate for Yandere?
- Would a Hanahaki scenario occur at all even if it's a minor attack? If so, why did it occur and how was it solved? Was it solved?
- If death were to occur, how would the Yandere react? Or alternately, how would the darling react?
*the next ones assume neither die*
- Would Darling be into Yandere's behavior or into them because of the bond's hold over them? *Do they find them toxic?
- Is the Darling scared of the Yandere or just slightly off put? *Did they come of their free will?
- Things Yandere does with darling
- Plans Yandere and Darling have for both of them
*NSFW*
- Is Yandere forceful? Do they Rape darling or even just harass her a bit?
- Sex Drive together?
- kinks? Positions?

Okay look forward to your feedback!
