to be fair minfilia and thancred weren't always close (there's a side story that goes into minfilia's initial mistrust for both her adoptive mom and thancred) but thancred has history with minfilia's mom and his crush never died hahaha
Minfilia and thancred mainly got closer together after the calamity, otherwise he was kinda in and out of her life growing up because it was needed of him working with louisoix
Yeah they don't super touch on this in story but basically F'lhaminn and her bf at the time were trying to pull a con that failed and ended up killing minfilia's dad, so that's why f'lhaminn took her in and minfilia had a lot of distrust towards them and stuff
the thirst is hilariousMe; the silent protag: ".........."
