Thank you very much~>>182289170 I'm currently phoneposting, so bear with me. Typos may occur.
Well, their wedding is not much covered. The deal about Chandra an Rohini is because they were a perfect match (too perfect for everyone's good). It normally say that he found the daughters and married them.
Chandra was heart broken because of an affair he had right before he met the daughters of Daksha. Chandra tried to run away with Tara, the wife of the deity Brihaspati. But it ended bad with the wife coming back to her husband and Chandra left with an warning.
Chandra most of the times is conected with the mind. And because of the affair the mind started overflowing with emotions (lust), so he found the daughters of Daksha and raped them, except Rohini cuz the horny bitch consented
And just like Chandra, Rohini overflowed with emotions (for being related with the moon as her rulling "planet"). Chandra fell so hard he did not wanted to leave his wife's mansion. Being in an endless full moon. Aech who's so cold and calculist (mind) couldn't resist his mortal curse, desires (love and lust). Specialy knowing that Craig is now a not so important piece that could be used in his 4D chess. Just one more signal of the mind losing control.
I can see that Karen might be the downfall and enlightment of Aech. Chandra and Rohini were so in love that Chandra started forgeting his duties and was cursed because of it - Maybe sensei can put some kind of curse on Aechmea.
But after being cursed Chandra decided to devote himself to Shiva and his curse was partially lifted. So Aech could end up in a bad situation, but after that he might learn a way to correct himself and the moonies and find Nirvana.
Hope what i wrote may help you anons.and it if also made some sense.
