If you read the story properly you will understand every bit properly. The photo and rumour in novel is similar to video and rumour with a difference is seme helped and uke fought for it. The author did a commendable job with the plot. Don't go with the rating of people who can't comprehend such things. Hope it's not dragged to only frictional and it's only a path for uke to overcome his cowardly/closeting personality and we get see the real one soon. It’s ended and feeling so bad for Jin yu.
