lol imma just put what i understood out there, doesn’t mean this sht correct.
both the twins have inferiority complex towards each other. aiji (omega) was jealous of the fact that seiji is an alpha, and that’s why he never bottomed for anyone except seiji (which only happens when he’s in heat and out of necessity). seiji (alpha) on the other hand, was jealous of aiji’s outgoing personality, and that’s why he tries to mimic aiji and follow his whims even if he doesn’t necessarily agree to it (like finding an omega they can have a threesome with). i believe that very complex they both have resulted to the incident where seiji bit aiji. since they have unsettled insecurities, in the heat of the moment the feeling of wanting to win over the other twin came through instead of being disgusted by their siblings’ phermones. that complex is also the reason why both aiji and seiji, at the start, didn’t want towa to differentiate them.
after the incident they only had each other, which made them move on from their insecurities and also rely and understand each other deeply. that doesn’t mean that what they have is romantic love, but they are mates now so it’s easy to misinterpret what they have for each other. but aiji still feels as if he forced that situation onto seiji (especially since seiji is the younger one), and so he tried to search for an omega that seiji can be new mates with. then towa came,(someone who wasn’t prejudiced) aiji saw how understanding he is since he was able to know about seiji’s side that he keeps in check (the flowers), and so he thought that towa will be perfect for seiji, and that’s why he started acting like an asshole towards towa (sex toys part).
seiji realized aiji’s plan and was trying to go along with it, as he feels like that will compensate for his wrongdoings towards aiji. but towa didn’t agree, at the end the two realized that the both of them are just trying to make it up to the other. obviously there were regrets and guilt but they realize that they didn’t stay with each other because of those feelings but because they appreciate each other enough, and so the drama ends lol.
as for towa i think both the twins like him in a romantic way, especially since he was the the catalyst for settling the twins’ complicated relationship. seiji likes him in an innocent romantic way hence seiji calling himself boyfriend and why he relies on towa in the chart. while aiji likes him in a sense that he wants to take care of him hence aiji calling himself master and why he likes towa relying on him. i think towa learned to love them both as he relates to their situation of not having anyone he can rely on in real life, and so in his way of seeking companionship he found a family (two partners he can rely on).
i can’t say this is a typical poly rel since it’s mostly the twins having a relationship with towa, and their relationship with each other is one of family and occasional sex due to heats.
anyways thanks for coming to my ted talk and i know this manga is not everyone’s cup of tea but you can’t deny that the art is supreme and spicy
it’s come to a full circle! in ch 5 of pendulum daato is seen in the vacation house apparently feeling hot and is revealed to be pregnant with twins!
