Kagamine Len
Because out of all the other fictional guys I want to meet, he seems to be the one with the least potential to stir up a ruckus.
Consider the following:
Sanji
He will, as he does with any other woman, shower praises on me and flirt relentlessly. Until a jealous Zoro comes along and discovers this. A heated argument which will last not more than 5 seconds and vicious fighting follows, then their physical fighting will turn into a make-out session, and... that's it for my meet up.
Gokudera
(omfg omfg omfg he's so fffffff here X3)
Gokudera: "..."
Me: "...um, hi."
Gokudera: "...hi."
Me: "..."
Gokudera: "..."
Me: "...um, how's your day?"
Gokudera: "Fine."
Me: "...let's talk about things you like."
*an hour long talk about his obsession with Jyuudaime later, a heartbroken Yamamoto shows up.*
Yamamoto: "Gokudera! Don't you like me too?"
And another heated argument will follow, which will result in Gokudera stomping off in anger and Yamamoto chasing after him and only god knows what happens behind that closed Vongola mansion door.
Renji
(Nooooo there is no picture of only Renji. Is he that unpopular??)
His gigai will blind me to death with the awesome hippie colours. If not it's his uber shiny well-conditioned hair. He is too hippie-awesome for me to handle. Period.
Takumi
(I've not forgotten my sec one crush! Doesn't he just reek of shota:3 I mean look at his face at the left AND TELL ME WITH A STRAIGHT FACE THAT IS NOT AN UKE FACE.)
I will pounce on me, and his sister and Akira will have me arrested for being a pedobear.
