"Sweet mother of crap." was all that your father could say to this sort of news. Although he cared about you as his son, he was somewhat glad to know that you didn't lie to him, despite that your girlfriend isn't exactly human.
But, after letting out a long sigh, he looked at you and answered, "Eric, I um.....I know that this might sound um, stereotypical but....no matter what you're going to do in your life, you'll still be my son." Then, shortly he after the words he spoke to you, your dad hugged you for a few seconds, then let go of the parental embrace, as you looked at him and said, "Thanks, Dad."
"Anytime, son." Your dad replied, coming to terms that not all Digimon are evil, especially if this certain Digimon has a crush on you and spared him at the same time. So, wondering what kind of Digimon you were having a relationship with, your dad rubbed the back of his head, looked at you and asked, "Just out of curiosity, kiddo, but what kind of Digimon is 'she', anyway?"
Although you did want to tell your dad about Lilithmon, you decided to leave out the part that she's a member of the Seven Great Demon Lords from the Digital World, since you didn't want your dad to start freaking out or anything related to panicking. So in response, you slowly fidgeted with your fingers as you looked toward your dad and answered, "Um Dad, she's a Lilithmon."
But suddenly, you felt something vibrate in your right pants pocket. You knew your cellphone was in your room and your 3DS was still charging, so you reached into your pants pocket and held what appeared to be a black and purple Digivice in your right hand. It was attached to a steel-grade chain clip that is used to attach to the side of your pants when not in use. Other than that, there were these rune carvings on the frame of the Digivice lit up by small white LED lights, which made your own Digivice look pretty unique in custom design.
When your dad noticed the Digivice in your grasp, he became curious about how it suddenly appeared in your pocket and said, "Let me guess; that Digivice you got came from Lilithmon?"
"Definitely looks that way, Dad. Back when we used to live in Tokyo, Henry told me that he and his Digimon became partners when Terriermon came from the Digital World through a Digivice his dad got for his birthday. From what he experienced, it created a partnership between him and Terriermon that has made them like brothers. But now...now it seems that I'll be going through some of the same experience as a 'Digidestined'." You answered, now coming to terms that there was no longer a choice to turn back.
However, for some odd reason, you were somewhat no longer afraid of Lilithmon anymore. You weren't sure if she did something to your brain's chemistry or if you were actually falling in love with the Demon Lord of Lust herself, but either way, you were definitely feeling some form of human emotion toward Lilithmon.
