Melli's Jealousy (Adaman x Reader)

He's been constantly pestering you since you started dating Adaman almost a year ago, but what will follow as you all reach your breaking point?

I was going to write this with a somewhat comical side, but oh boy let me warn you now that it did not come out like that. This one has a fair bit of angst, but I like to think the fluff makes it all worth it. This is another short story that came to me in a flash of inspiration, so I hope you enjoy!

I guess minor spoiler warnings for the plot of Legends Arceus, but this time it's nothing major!
