Hi author ! I just read your book and this caught my eye . It's the first time reading Mahabharata BL so please don't end it. Also one more question is duryodhana and yudishthir going to end up together?
Also, You wanted an idea on how Karna and Krishna should meet. Here's one. It may not be good but it combines the ideas of my friends too :)
How about krishna first arrives in Hastinapur himself to meet his kunti bua . Then to reveal y/n . Or krishna could meet the pandavas in their exile only . Like the one after mera matlab ki ussi beech main jab pandava ghoom rahe ho lakshagriha ke baad. Then they reveal y/n . Of course, y/n should have a love interest too . Hehehe:) , And that's when krishna and Karna will meet. Karna upon seeing Krishna will have his past life visions because of which he will get scared of Krishna and will want to avoid him. Krishna gets irritated by his behaviour and confronts karna. Karna confesses to krishna. Then you can focus on yudishthir and duryodhana I guess .
