You are Alfe, LeiLei's stepsister. LeiLei has just come back and has surpassed you in every way, even stealing the man you wanted.
What would you do?
How can you even hope to keep up with Best Girl?
>Lelei considers herself and Itami to be married as revealed late into the story due to the "Ceremony of Three Nights" as hinted at in chapter 38 of the manga.
>The Ceremony of Three Nights is explained that if a man and a woman sleep in the same room and/or bed it announces their relationship publicly.
Yeah she was only adopted. Alf, I mean.
