Don't count on it, the sex will go badly somehow. He won't be able to get it up or her mom will walk in, or something. It will end badly, mark my words.
They lived happily ever after The (happy) end
But seriously, I'm curious to see how they'll fuck up now. There can't be rapists at her home, right
Or well, he probably ends up avoiding it so Iida goes looking for someone else...
