Do...do cupids kill other people to make more cupids? Now I'm wondering if Koharu's accident was more than that.
Kanna was masquerading as Koharu's classmate in her flashback, though I'm sure in her case her aim was to make her fall in love and Koharu's death was a genuine accident she was powerless to prevent. Here though, it certainly looks like Sae caused Ena's death on purpose.
Good point. I remember noticing that girl on the right looked like Kanna. I want to believe she had good intentions!
