the way 'like mother, like daughter' writes about abuse and somyung and sol's relationship is gonna make me rip my throat outttttt
the different ways each of them reacts to their own abuse: somyung by becoming more resilient, confident, and assertive, because she needs those traits to escape her mother, but they're ironically traits that were cultivated by her controlling mother opening doors for her and seeing after her future success; while sol blames and hates herself for everything that goes wrong and shuts down her own feelings, because she experiences getting relentlessly criticized and forced down paths she doesn't enjoy in the first place, leading her to feel like a failure at every turn.
and the way these reactions mesh, how somyung is the only person to see and call out the way sol is consistently put down and treated badly by people who should love her (her mother, her friends), but interferes with sol's life in an increasingly controlling and manipulative way—even if it's "for sol's sake"—and replicating her own mother's way of raising and loving her, which was by setting somyung up for success and forming her into the "ideal daughter", even if it meant ruthlessly culling any obstacle dragging her down.
