By toxic, I meant that their relationship isn't a healthy one. At the beginning, Taehwan has stated that their relationship is purely a pleasure/lust one, aka they fuck buddies. Even if Taehwan knew Yeonwu liked him, he would've just broken off their relationship. He don't want that commitment.
Ok, maybe Yeonwu likes it a little rough, but even then, they haven't ever discussed how far things could go, or even a safe word in case things do go too far. The power dynamics are also a yikes. It's basically one sided.
I don't know about you, but that should br considered a toxic relationship.
We all know Taehwan is probably end game, but I really like this Alex guy. I feel like with Alex, Yeonwu would feel more comfortable in his own skin. He did mention his sexual orientation vocally (for the first time) in front of Alex, and doesn't have to suppress his feelings. Not to mention Taehwan and Yeonwu's current toxic relationship.
Anyways, I'm looking forward to seeing their relationship progress (though probably just as friends).
But, whatever makes Yeonwu happy I guess. ٩(๑❛ᴗ❛๑)۶
