What's your top tier BL that has the potential "poly" relationship, or "could be a poly" for you?
I mean... this one is interesting. The list is not actually huge, but I will do my best to capture them all!
Light On Me (DaonTaekyungShinwoo): I mean, this is what a love triangle is about! So how can I possibly resist them being adorable and adorable and never having to chose even though I know Shinwoo will win in the end?
Y-Destiny (TirMasukJia): Practically canon! I mean, basically canon. The only reason it isn't canon is because Tir is dead and, let me be clear, that will never stop me. Especially when he's watching over them at all times.
Y-Destiny (KaengPuthPayu): Do I have the same show here twice? Yes. Do I care? No. This is about shows and polyships and I think this show needs to be here twice for two very different polyships. So here we are! This one is far, far less canon but I think still has potential.
Brothers (TriMabMob): My first true and instant polyship in BL. Seriously. The twins both agreed to love Tri hopelessly? How am I supposed to resist the idea of them actually getting him? It's beautiful and holds so much potential and is absolutely hopeless.
Gen Y (MarkKitYu): Honestly, this polyship has taken a while to grow on me. But it has now. I've grown very attached to the idea of Mark and Kit rescuing Yu from his own constant need for romantic attention to feel worthwhile.
I think these are my favorites and top tiers for poly, honestly. Are there more that have a chance? Yes, but for the most part I don't like the poly or prefer the plain canon.
This goes for My Engineer where, yes, I could do BohnDuenFrong but frankly I'd rather just break up Bohn and Duen so... you know.
And, yes, that potential in FUTS but I think Mueng Nan and Mork are both toxic people who just need to stay away from Pi, thanks.
So, yeah. Top Tier polyships, basically!
