My theory for the Break X Shelly.
Given the sweetness that the young woman gave him that Break wanted to commit suicide, it is normal to be attached to it. Saw the look he gives her in this picture, it is clearly love eyes ( But just Break, I think not for Shelly. )
Now she is dead, Break reviewing Shelly in Sharon. He vowed to protect her because it was the last wish of his love.
But now, it’s just my idea.
