You are Shuichi

Kokichi runs over to you and jumps right on you, tackling you with his usual big annoying grin on his face

"Hiyaaaa!! Shuichi~!! How about you forget those investigations for a little while and play with me~?"

He doesn't get off of you and doesn't seem like he will get off of you anytime soon

"..Ahem.. Anyway! Did you miss me? I bet ya missed me! Ofcourse you missed me!!!"
