Izuku and Momo is married and have a son that is named after Izuku himself. They both have a great relationship where they always talk to each other without getting offended at each others problems. So far everything went well until one of Momos childhood friend Shoto Todoroki came around the thing is Shoto is a manipulative narcissist who wants nothing else but trouble. He once heard that his childhood cray is married and already have a family so he left to go ruin it just so he can have her. When he saw Izuku with her and a little boy he doesn't stand the fact that Izuku looks better then him and making Momo happy along with little Izuku. Also he doesn't like it when people fight back especially the strong and he intends to run away when things don't go his way.
After he saw that he thought of a way to break up the family if he was to either get Momo to cheat on Izuku and leave the little boy. At first he thought of just showing up and taking her away from them but he see that would be too easy and such he has decided to do the impossible and try dragging Izuku into being a mean asshole towards her as he can have the both divorce. Little does he know that the drug will be little effect to Izuku. When he shows up he introduces himself as Momo was happy to see him as Izuku just saw it that she's normally happy and allows it to be when Momo turned her head back around Shoto gave Izuku a cold glare which Izuku wasn't afraid of as he was confused as to why he gave him the cold look. Just as he turned his head he saw something that Todoroki did as he looked back quickly to the point that he thought he saw him do something but just shook his head.
Izuku: what did you do?
Shoto: what do you mean I haven't done anything.
Izuku:(something tell me that he did something he is suspect of something) very well then
As Izuku took his cup not aware of the drug that will take little to no effect at all and finished his cup with a gulp. At first he felt a bit funny but soon it wore off for some reason to him he wanted to tell me to stop playing with his son but his urge resisted due to seeing his family happy. Not knowing to him Shoto was smirking his ass off knowing that he won Momos heart already as he looked at her playing with the boy.
Shoto:(soon you'll be mine and that you will have a sad life with me and that you'll never trust us men am ever again)
Soon days turn into weeks as weeks turn into months Momo have been realizing that Izuku have been acting strange and she started to worry about him as she talks to him.
Momo: hey honey are you alright you been acting funny ever since we seen my childhood best friend please talk to me.
Izuku: I don't want to
Momo: Izuku do you not trust me as your wife?
Izuku: I do but
As she softly grab his face and made him look at her as she put her forehead with his.
Momo: tell me please
Soon the effects somewhat wore off as his body fought off the drugs that Shoto poured into his drink.
Izuku: I-I think that your childhood friend did something to my drink and that I drank it all as well I think he out drugs into my cup.
Momo: but your a dragon nothing should happen to you. But um why would Shoto do something to you he's a nice friend.
Izuku: when was the last time you seen him before that day?
As Momo tried to think back the last time she seen him was back in middle school.
Momo: ok your right he could have changed but-
As there's a knock on the door as they both looked at each other as Izuku got his transformation ready just in case.
