Now hold on a sec Yatty! Usually the childhood friend loses in love, so at least we've got childhood friends destined for each other (because we know that the first person MC lays eyes on (the trap) is the winner).
I agree that things will likely go that way. But, given the presence of traps and a trap cafe central to the plot, childhood friend girl has to beware of her dude being smitten by another dude.
