for me at least, it's because boogie isn't willing to be upfront about everything and admit that he just wants a thin young trophy whore to show off and travel with. he needs some grand justification to sell the relationship and for whatever reason he chose to push the narrative that they initially bonded over both having trauma. a near 50 year old man fostering a relationship with a teenager (at the time) who just graduated high school two years ago by using her trauma as an in to connect with and relate to her is pretty fucking gross and creepy. boogie needs to keep his childhood molestation stories between him and his therapist, not whine about it to teenage girls to try and relate to their daddy issues. at the end of the day, yeah it's legal, but he's still a creep and also a faggot.
