The fuck? The way you express yourself makes you sound like a misogynist.
Yeah, silence character acts different. But it is implied that she stated to do so because she caught feelings for Lee Han and wants to protect him, and also Lee Han reminds her of her old team mate who possibly died. She literally is more powerful than most of the squad members. The fuck.
And the blue hair girl is terminally ill. She is literally forced to use her psychic powers that are killing her for the sake of "humanity". She has all the right to act like she does. Annoying yes? But if you had a little bit of empathy in your soul instead to act like a fucking asshole you could at least understand her. Both silence and the blue haired girl are complex characters, this is not a "no feelings macho manhwa".
Until Ch 50 silence was presented as a man and behaved as such. Ch 64 they gave a glimpse of a feminine face and i realized even the character drawing started to look like a woman. Moving closer to the MC and following him around. Then here comes a blue hair selfish bitch called the oracle that with held valuable information because she wanted everyone to die with her. Female characters are problematic. Paused at Ch 69
Update: Reach Ch 70 and silence started to get jealous and take out her frustration on another squads team. Women always mess up the plot, only stayed for the blue eye dark skinned cry baby
