what the heck! why don't all four of them meet up and talk about what happend between Junpei and Rina. What is with all of this calling and talking about something so serious as cheating over the phone. Both couples need to talk in person because all that is happening with the phone calls and the one-sided stories is more confusions.
But would you believe what they say even when you all get together and try to explain. It's not that simple.
Aww they made their own family... so cute (▰˘◡˘▰)
