"Unknown" Malay boy ? U dunno him and want to
friend a creep who stalked you and obtained your number ?
means he like you
Yeah he probably likes you. He put effort to get your number from someone else, and yet be doesn't want to put effort into actually talking to you in person. Maybe he's shy or just stupid, or a genius mastermind with an ungodly plan to secretly and slowly get into your undies. What you should be doing is ask what he wants, and don't need to say Malay boy, boy means boy regardless of race, say asian instead. Tell him the facts that its major creepy when a stranger sends a text to a girl(assuming you're a girl) and not being truthful about he's motives. If he says he just wanna be friends then hey, be friendly, he might turn out to be really good one. So long as you don't put yourself in danger and go on a date with a stranger you know next to nothing about. (You can actually make friends through text)
