Junha isnt the type to do selfies, not all people do selfies even with their lover. Jinha misspoke because he was panicking and well too blushy-blush, he doesnt mind having a picture of his lover but seeing yourself in that picture with your lover, it feels so wrong or lets say cringe (idk whats the right word) plus Jinha wasnt the one who took the selfie with that 'friend' of his he was being forced, and before he can even react that friend took a picture already. In other words, Jinha likes seme--no, he loves seme he is a tsundere! And him being in the same photo with his lover its........idk the right word but cringe is actually like the closest one so I can relate to him. He really really REALLY loves seme he is just not expressing it well in words so I understand him lolol and seme misinterpreted his lover's intention which I cant actually blame both of them cause misunderstanding is quite common in relationships (platonic and romantic). ヾ(❀╹◡╹)ノ~
