I wonder what Gaku would’ve done if Kunimi never reached out

Well... Kunimi would have tried to kill himself again.. And maybe Gaku would have tried to reach out too.. But when it would be too late... That's... How i wanna interpret ot, at least.. Or maybe Kunimi would not try to suicide again... But still Gaku would have been too late to reach out i think... Cuz... I just have a feeling that Gaku has that kinda luck because of his overly shy and a bit of an air head nature
