I can't with people being flat-out **disgusted** about actors age gap, lmao, it's just fiction, acting. If you still don't like it, just ignore this drama, no need to be insulting and damper other people's excitement. My bff met her boyfriend of a similar age gap as this when she was around 14 years old, so I really couldn't careless about age, it's just that, a number. xD
