Here something to clear this up; The Title "Don't get attached" is something Kumo(The red character) tells herself each and every time she be-friends someone. She pushed away everyone, including the only person who truly understood her. That person being "Lian"(The spacey character). She'd always be rude, coming across like she didn't care for him at all. Even though she cared for him and only him. And in their last battle together, he was killed. He didn't drop dead, no, he exploded into tiny particles of star dust- filling the air of the battlefield. He died right in front of her. As she slowly realized the mistakes she made, and how bad she treated him- she was filled with eternal sadness.
