I'll save you the time and tell you what I think.
I just think that they're kids who are just taking an interest in each other like experimenting and I don't really see a much problem with that. Yeah, It's freaking weird, I know but ultimately I don't really think that way and tend to let it be because they're not doing any harm to each other and actually helping one another.
So yes, I don't mind If hal and lippe in particular are considered being a potential couple. Maybe, it's just preference and me being me but that's what I think.
I think I may be a bit contradictory to my precious comment. Sorry, I tend to panic when someone replies. I'm terrible at arguments.
