I'm looking for either a manga or novel where the mc is a huge bad ass warrior or soldier but doesn't know how to live normally.They have little emotion and only know fighting. You get the idea. But then they have to live a normal life or they are brought in by a family and are taught how to live and have fun. 😀 😀

Parts of Sengoku Youko are a bit like this.

Sasen mo Warukunai A soldier learns how to live life outside of war after getting married.
