DY was very gentle and asking for permission to continue if YJ couldn't handle his insertion for their first time. Also, he didn't know about YJ's feelings. If he did and still played w his heart then yeah. Also, he got mate bonded against his will and the omega ran away, so prob DY broken up with YJ cuz now he's been marked. Yeah it's sucks he's not using a condom but....YJ cannot be impreg outside a mutual heat and rut coinciding...and we'll, chances are low, but unless the alpha release inside him.
I mean, unless he's been w/ other betas before finding YJ then maybe chance of STI but not impreg
does he think his toxic ahh can even raise one?? Geez.. also he's not using a condom. im scared for yejun :C also were getting flashbacks now who knows for how many chapters... but seems like the seme was always a nightmare dressed like a flower
