Ngl I would have caved Gren is really trying and there is something special about a sibling bond that I have a soft spot for. I feel bad for Gren even if his obsession for Shin is tipping the unhealthy scale but it gives him hope and I really want Shin to try with him as long as he sets proper boundaries he doesn't have to completely cut Gren off.
I know all.of this is wishful thinking and something really terrible is going to happen. (〜 ̄△ ̄)〜
