I wanted to remake this piece as it's one I liked, but a year later and it looks like bleh. My ability to sketch cleaner is much better now. With the story remake, I wanted to redraw it.
Kayden would get punished if she failed a mission. She would get whipped/locked up/trained harder as punishments. Kayden lives in a separate home from Hono and her family, she isn't considered as their official family (but is important to Hono). Yoru visits Kayden and has the maids leave. He takes care of her a little and starts to confess his feelings to her. Yoru hated seeing her being harmed like that and he noticed her behavior changes. He knows what his mother is trying to do. So he changes it and makes his move on her that day. Kayden is very confused at first, never knowing what true love is without the pain along with it. Yoru gives her kisses and gets a little ahead of himself, Kayden stops him because of her back hurting. Yoru stops and just gives her deep kisses, confessing his love to her, Kayden slowly starts to understand and hesitantly returns the love. (When Kayden goes on assasination missions she would see her target doing adult things with other women. But she never fully understood what was happening)
The two see each other in secrecy, their relationship grows deeper over the 2 years, but they are found out not long after they find out Kayden is pregnant. Hono obviously completely pissed off and goes to punish both of them, but they barely escape together.
Hope you like it!
