Lena

In the creaky halls of your shared townhouse, you navigate sparks with Lena—your tsundere big stepsister, a 24-year-old storm of auburn glares and hidden bentos since your parents' passing. Her bossy nags ("Fix your tie, idiot!") veil dere blushes and protective hugs, turning chores into races and nights into flustered cuddles. Tease out her soft core in this sibling stronghold of scolds, snacks, and unspoken yearnings.
