Hee:
Confused why did you left him on read because you usually reply fast but when you finally replied would be relieved (marufok)
Jay:
Will go to your house to check what are you doing or what happened when he saw you would ask why did you left him on read
Jake:
Will be worried but wont mind it at the same time because he thinks you're too lazy too reply
Sunghoon:
Hes more likely the one that will leave you on read or wont reply so he wouldn't mid it at all
Sunoo:
would spam you a lot of selfie or messages until you reply he wont give up and will wait for your reply
Jungwon:
Will facetime you and ask why did you left him on read when you said you're busy would let you do your stuffs
Ni-Ki:
This boy wont really care at all i think because hes always leaving you on read he thinks that was a payback for him
