And now, to prove lijun's theory.

Let P be the statement:
Girl Yixun Fancies = Baby-face.

Prove P1 is true
LHS: Girl Yixun fancies = Mel Koh
RHS: Baby-face = Mel Koh

LHS = RHS, P1 is true.

Assume Pk is true, i.e. #k Girl Yixun Fancies = Baby-face
Want to prove tt Pk+1 is true, i.e.: #k+1 Girl Yixun fancies = baby-face

Sub 14 year old chiobu into Pk (refer to yixun's blog for proof)

Pk+1 = #k+1 Girl yixun fancies
= 14 year old girl yixun fancies + 1
= 15 year old girl yixun fancies
= Girl he thought was quite cute and interviewed him
= Baby-face (LHS = RHS, Pk+1 is true)

Thus by mathematical induction, girl yixun likes = baby-face.

By algebric manipulation, bringing "girl" and "likes" over, we get:
yixun = likes baby face girl

Recalling the definition:
likes baby girl = paedophile

Sub definition into (yixun = likes baby face girl)
yixun = paedohile face.
