I'm finishing this for the same reason finishing Tossara: I started and it's only a few eps. Why did they do this?…
but they did kiss in latest episode and maybe neither of them have been with a guy before so they are careful. Also, they haven't seen each other in awhile and were starting something end of season 1. It's the beginning of something and we aren't sure they are in a relationship yet. Tossara was great also, it had even more than this show.
The only ones who have been open about it at one point. They both had boyfriends. There's the whole Mew kissing Art thing but we don't know what happened.
