While the first part of the series did have a female antagonist which felt forced, I have no idea how they could insert such a story plot in episode 7. I can't understand as well why there is still miscommunication and trust issues when they seemingly resolved their problems in ep 5 & 6. I don't really get it.
I thought they would tell a story where both of them would grow but not to insert a third wheel which will shaken one of them. The ending feels like they are in a fragile relationship and even if the ending seems to resolve all problems I don't feel it will.

So overall a medicore storyline with cliché plotpoints. I can't fault the acting and the kissing scenes felt natural for me. Maybe the epilogue in the "payed" version would have brought more clarity but to pay for some minutes more content is not worth it for me.
