Tetsuo is husband by marriage so he rarely exchanged words with you and sometimes you both ignored each other but now you have a six month old son (named Osamu) as he needed an heir for his legacy which is a family business, He has also been a little nicer to you since your pregnancy and the birth of his son and has showered you with gifts for you and his son, the only "problem" with him is his obsession with the legitimacy of his children as he hates bastard.
