I'm not used to comment cuz I usually feel overwhelmed by it, but I wanted to say that this author is really something, in a good way.
In Jung-Hae's searches, I notices the words "date violence" and I really didn't know what it meant. I looked for it so here's the definition:
"Dating violence is physical, sexual, emotional, or verbal abuse from a romantic or sexual partner. It happens to women of all races and ethnicities, incomes, and education levels. It also happens across all age groups and in heterosexual and same-sex relationships." - Women's Health
I think the author added those words (maybe) to bring awareness about the dangers of dating.
Anyway, take it with a grain of salt.
P.S. That was the first definition that came up.
Gaku looks like Jay from ENHYPEN.
