I don't know if they were talking about pheromones in omegaverse but in real life pheromones can talk about a lot of things

Maybe he pretends to be a boy so that the loan sharks won’t sell her (⊙…⊙ )

My thoughts exactly! And I find Theo's reaction normal, actually. I'd be in a whirlwind of emotion if I went thru the same thing. Having an irresponsible parent, experiencing loan sharks going after you, afraid of seeing the only person you depend on do the same thing as your own father. Needing to hide because of the possible threat of catching you and selling you into child prostitution... yeah, I'd lash out and say some hurtful things - because of the fear and the betrayal experienced when they were younger (and Theo is still a child).

Theo suspects Craig, since he usually isn't around. She has a bit of trust issues because of their father. Craig is doing all he can, even if he's already drowning in despair - he worries about his sibling. Theo does care about Craig, too - though I suspect a hint of tsundere. Besides, it looks like whatever she would be saying to anyone looking for her brother could have already been agreed upon (previously) by both of them for her safety.
If they fell in love in highschool this wouldn’t be an interesting manhwa ( ̄∇ ̄")
