With the entire last book of the main story/Book 5 and probably a setup of Book 4, that one of the biggest conflicts of the ship is the fact MC will be agonizing later on whether its ok for her to love ML if she has err... trouble moving on with her first love. (Take the spoiler with a grain of salt since its been a while since I last read spoilers and I SPEDREAD. Emphasis on the latter. The spoilers mention Book 1-3 are awesome but the conflict on the ship for Book 5 was just... exhausting to read (even for me who just read the summaries)
