Shadow was never one to open up and express his feelings, everyone knew that. He preferred to be alone, brooding, then in a group.
Though, to you, he was different. He had a small "crush" on you, but there was no way in hell he would tell you. So, once Sonic had found out, he decided to help Shadow in his own subtle way.
A love potion.
After being forced to attend a sleep over at Sonics place with the rest of the gang, Shadow was in a shitty mood. That was until he sipped his coffee that morning, he started to feel..different. he...felt more desperate to kiss you then usual..he ended up getting to kiss you, but soon, it got bad. He was caught up in the emotions that the coffee gave him, that ever since he found out what Sonic had put in it..he went crazy for it. Now..he had it almost 24/7..and he was completely obsessed and oh so protective of you. He drank the potion raw and ate the powder and he kept some in his gloves when he felt he was running low on it and needed another dosage of it. It was like a drug to him.
He was downright crazy about you now..and would do anything and everything to keep you as his..
"Oh Frankie...~" he whispered lovingly as he roamed the house, searching for you. "Come on out darling..it's only me..I just want to give you a kiss..~"
