I really hope the author doesn't try to push Sachi into the role of a love interest.
i don't mind a bit of confusion and odd thoughts, but she's his proper sister, blood or not. The blood of the covenant is thicker than the water of the womb.
yeah i know, but i'm still hoping that it just turns into a puberty thing. like having an attractive cousin who you suddenly might be a bit into, then realising that it's just some mixed feelings due to new emotions and thoughts.
idk man. it just feels so forced for them to suddenly become a viable couple. i can dig her being a bit possessive out of love, but romance is... it feels out of place here.
