I think you're right
That literally makes no sense. A toxic relationship should be used for “growth”. Haesoo experiencing s healthy relationship with Taku while also trying to recover from the toxic relathionship with Joowon bfull of manipulatiom and deceit can also be used as a means for growth. If he dates Taku that does not mean that they are gonna run off together with the sun and flowers shining on them. Haesoo will have to gain self-confidence which has been greatly lessened by both his job and Joowon, and also learn how to accept having someone genuinely love him without all the mind games. He doesnt have to be with Joowon to grow. Taku with his bluntness can help him by allowing him to be secure in their relationship. He never shies away from telling Haesoo how he feels or how much he likes him. After what Haesoo has experienced with Joowon he needs that. So that reasoning makes no sense.
shouldn’t*
I never said it's the logical end pairing and i didn't mean that their toxic relationship should be used for growth, it's simply in this story I personally, key word:personally think it'd be more interesting to see growth in haesoo/joowon pairing than to see the course of taku/haesoo pairing. I also never claimed to be rooting for a pairing that makes sense, I just think the joowon/haesoo scenes are entertaining
But he's too late, he's let their relationship stay toxic so long and now haesoo is falling for taekyung. I'll probably get downvoted since everyone seems to be obsessed with taekyung but I find the forbidden nature of joowon and haesoos relationship more interesting than the roses and butterflies relationship between taking/Haesoo. If haesoo and taku officially date, thats prettt much the end to the story since as a couple they won't have to grow as much since they are the healthier pairing looool
