honestly i think sions actions are valid, both sion and jun deserves better, it's just the misunderstanding of both of them sion knows that juns works w her mother in order to resurrect but jun actually against on this despite being a childhood friend w mc, sion doesn't know juns side, on the other side jun despise sion from being the son on his master and feels pity on mc thinking both of them deceived mc but that's not how sion is, sion was being like this because he is not ready yet, waiting to become the head to gain power, to protect his self and lea, but all i can say to sion is " right person, wrong timing ", jun got lea's affection first, i hope lea will soon know what's sions going through his mind...💕💕💕
