from Sacred Stones: Ephraim/Eirika, I liked their sibling relationship a lot, I'm a sucker for those.. (not romantically tho)
Fire Emblem 7: Matthew/Serra
Fire Emblem Awakening: F!MorganxLon'qu I know that's kinda weird and not possible in-game but for some reason I really really like it? I imagine that male MU is very protective over his daughter so usually he sends someone he really trusts (like Lon'qu) to guard her in battle. And usually she is very cheerful but as she gets snippets of her memory she starts breaking a little and Lon'qu gets worried/helps her.. in my head i swear this made more sense but I forgot most of it XD
Villager: Does your sciiiiiienceee explain why it rains?
Sokka: YES! YES IT DOOOOOOOES
