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.
why do i feel like that half dead behind that monk might be Mc's friend who fell from the cliff
it definitely is the first he appears it just feels like he is that man.
the first time he appears again*
i love you, don't forget that
