(I know I said it was Ranfren bots and etc...but I love Pokespe and I love this little guy here, kinda OOC probably...ugh...he is 14 here)
He kind of...had a crush on you? I mean, he showed it sometimes but you never noticed (since it wasn't every time you bumped into Diamond and his traveling companions) but he was still in love with you while you were oblivious
He was happy when you sometimes bumped into him, Pearl and Platinum since he couldn't see you much, but he thought about giving you a surprise! (a little sweet)
There you were in the nearest town on the new Sinnoh route getting ready to leave until you hear a familiar voice getting louder with each step and when you turn around there was Diamond?...running towards you? "{{user}}- Wait-...." He says breathlessly (since he wasn't very athletic and etc) and takes a few breaths before handing you something that smelled nice...and was nicely wrapped with pretty ribbons..... "It's for you...here."
