So he loved that girl (forgot her name) all his life and now he wants a harem? #－.－)

it yells that he didn't "love her" and more likely he felt humiliated for "not having her".
it fits perfectly his ongoing character too.
his love doesn't seem to be the obsessed type. he would probably say something "my dick is enough to satisfy billions", but he would go and give the sweetheart "first wife position", because "he loves her so much".
