DoJim pissed me off this chapter

I know it was presented as funny but didn't he use to date alphas all the time before ending up with hyesung, what's he whining about?? Also it's bad of a parent to snoop on their kid like that, wouldn't keeping an eye on them and waiting for byul to feel comfortable enough to share his love life be the more mature thing to do, now the kid's just going to try to hide his personal life even more than he already was. Been there done that
