Tbh they should've gone all out and made it clear that they were going to be a poly couple. Keeping the ambiguous siblings relationship when both of them love them is weird. Specially since the older sis is minimum 4years olders with the younger own being younger by 2. With that difference they might be pushed by the parent to get a bf/gf making weirder to come up and say that both of them fell for him. They should've kiss when they woke him up at ch 31
