I was asked to find the chiral center and write the two enantiomers of 2-methyl-1-butanol

I don't understand why the two answers which are given in fischer projection have a CH3 bonded to a C and that C bonded with an H and a CH2OH on each side. isn't a methyl group a CH3? so shouldn't the C have a CH3 on one side and the OH group on the other side? how would I draw the enantiomers for this molecule
