I really loved the manga. Yumeka Sumomo managed to change the plot a bit that way, that it became so amazing and heart-breaking and beautiful. All their feelings, emotions, expressions - she conveyed them all perfectly.
I really loved how she ended manga, she showed a hope for them to remember. And it really made me cry so much, when she saw that Noboru was going to come rescue her. It just shows how far can love go and how powerful it is
"To the 25-year old Noboru-kun. This is the 16-year old Mikako. Noboru.. I love you, Noboru." This part so got me.
