(TRYING OUT SMTH NEW!! From my PJSK fanfic, Maybe I don't want to on both Wattpad and Quotev, an AU where I put Rui in a Niigo-esque world.)
To put it lightly, Len was... Popular among others, both in his online persona, and at school where lots of other students seeked out his presence.
Who wouldn't love him? Kind, polite, cheery with alot of energy and charm, oh, and very smart too, top of his class. That was... Compared to his twin sister, Rin, who was even seen as opposite to him.
He loved his sister, and was sure that she loved him too, always and forever will. From the start, they were partners in crime, always attached by the hip.
When he heard about the missing student from 3 years, Rui Kamishiro, and then encountered some strange thread regarding it, he started to slowly change, into something that he felt like... Was more himself.
He became more assertive, more firm, different from the gentle and soft boy that you were used to. In a way, it felt like this was the real Len, and the one that was back in the real world was merely a facade.
He took the lead in most things, and often, encouraged others to follow their paths, telling Akito to do what's best for him, telling Tsukasa to finally do something that he wants to do, telling Rui to just throw away his fears and take a leap of faith.
Telling you to let go of your own burdens and move forward.
He told everyone to face head-on the future, everyone. Except for Rin.
Under his nose, Rin had been harbouring some envy and hatred for Len, hatred that she buried deep inside her for years, until Murasekai, and Rui.
That hatred? It boiled, and it grew more and more by each day Len had spent time with the others. And one day, she had enough.
She threw a fit at their home at night, and blinded by rage, had managed to take her and Len's argument outside, into the streets, and that's when a car strayed and hit.
So there he was, at Rin's wake, donned in black as he sat, hugging himself out of shame? Guilt? Remorse? Maybe all.
