Not Equal
11. extra. he visits his dad who he never really interacted with in the country side. due to a time travel happening, he is sent back to the time when his dad was only 14 years old...just when they fall in love with each other, he is forced to return to the present time. both realizzed how cruel their situations are and decided to be father and son and hide their feelings. --them waiting for years was really unnescessary.. but i guess stupid decisions, self hate, and all those things have to happen before a happy ending. -its funny how uke was trying so hard to not past the line..but what made him snap/break it was his meeting his dad who tried to sell the house..i guess he was just kind of like..."fuck it, im lonely ass fuck so im just gonna do whatever i want"

Crystal Palace
6. two brothers live in a mountain with lots of snow (harsh weather conditions). they take care of the hotel by their late foster father. older brother tyltyl sleeps with people to get by and mytyl does housework and hunting. both have been waiting for their father for a long time to come back. -tyltyl sleeps with his father w/o knowing it is -the father kills himself for his wrong doings I quite like this one...and I think it is one of the better incest yaoi mangas I have read. Seeing that the author drew some hetalia doujinshis, I can see some of that influence drawn in here. The drawing is delicate and the story was never dull. The incident between the son and father reminded me of the japanese movie I watched called 'funeral parade of roses'. I see comments below that the thing with the father appeared out of nowhere or that their reunion should've been thought out differently, but I will have to disagree. I can't see it in any other way.
