Tenma and Yoshio they have an entire manga on them its called "Mayonaka Drastic" plus a prequel called Yoru mo Hi mo Akenai

From what I can tell from the raws this whole manga takes place right before they get together officially. The next chapter goes back to probably... right after high school possibly college.
I think that ch 1 is current timeline so they are together... but Tenma is hiding feelings about something. They have a very strange relationship, so for all I know I'm far off.

anyone who is reading this can tell me whether his father marries this new woman ..like its a contract marriage or love marriage ..??

I can’t remember the details. I think they already married. I believe it’s a marriage of convenience and power, but it seems to me that they have mutual friendship and respect. I kinda feel like she has feelings for him. I like her a lot. She’s caring and loving to all those around her. She is an equal to the father and Carrie’s herself that way.
watarun took miki's feeling for granted & by the time he realized his mistake it was too late ...although i am weak to friends to lover story but i am happy for Miki & Hasegawa ...
Me too, miki deserves a boyfriend that truly cares about him. Watarun is selfish and lowkey a dick
