Mello feels a twinge of guilt for what he did to Sayu. He pays for her treatment anonymously. If he had lived, he would have sent Sayu and her mother money regularly to make sure they were well taken care of.
big bad kira’s soft spot for his sister oooooooohhh (⃔๑⃙⃘◡̈๑⃙⃘)⃕↝🤎🧸 (still haven’t watched death note so is this their actual dynamic?? if it isn’t, don’t bother replying)
I just can't get over how cute the Yagami siblings are! <3
Like look:
Light bragging in front of Sayu while she cheers him on? ADORABLE
Light doing Sayu's homework helping Sayu with her homework? So endearing!!
Light's FOND side-glance towards his sister? Absolutely Lovely!!! <333
Just look at them gooo :D I especially like Light secretly smiling to himself :DD
Oh and did I mention? Sayu's the only one perceptive enough to notice little changes in Light's personality (although she mistakes its cause of course). Like Sayu is close enough with her nerdy older brother to know the lil differences <3
