Difficult to understand

"I swear I don't understand!" Paijo grumbled.

 Johan, who was being Paijo's friend, could only shake his head slowly. Of course this is Paijo's fault completely! How could he say something like that to Melody?!

 "Come on, you think, where is my fault? Since that incident, my phone has never been picked up, I've never been to his house, no one has ever had! There's a lot to take care of, this is what we both want to marry, not just me. indeed!"

 "Can you be a little more sensitive, bro?!" said Johan.

 Paijo was silent. He gaped at the words that came out of Johan's mouth.

 Where is the point of insensitivity?

 "Obviously, when you say it!" cried Paijo in annoyance.
