Tale of the yellow dragon - (the ending is bitter sweet)
Taming the tiger - (The ending made me cry but there's a side story for those who wants a good ending)
Dance with the devil - (3 stories, it might be boring at first and the art is not that good but the plot is worth it.) I still cry everytime I read it because their love is was painful but heartwarming at the same time.
Life senjou no bokura - I cried because the plot was realistic, which might or does happen in real life and I feel pity for the uke.
Jazz for two - made me cry for the situation of the father. Love the plot as well.
Killing stalking - you might have already read this but I still want to write it because it's the first story I read where I bawl my eyes out.
Ps: I don't know why I'm tearing up while writing this. o(〒﹏〒)o
