This bl is more on flashbacks, that's why its kinda confusingly, the author also didn't specify or do any warnings, it made it more confusing. But if you think deep on it and read the other stories it be more understandable. And their thoughts also are more on riddle, while reading this, I was also confused

After reading this again, I can say it is definitely not because I did not read the other manga. Most of the explanation required is already provided in this in the form of flashbacks.
I think the main issue was the long hiatus for me. It became very confusing to keep track of the story. After re-reading, I can make sense of a lot of stuff I was confused about before.
But I still felt that the dialogs did not make sense in some scenes. Like who is thinking/talking about who and such.
I wish I understood this. Read the whole thing but still some parts make no sense.
