Yoshizawa Kenji in Fake Affair is a second lead who deserves a second chance. He gets married to Youko in his/her 30s and after few years into their marriage he wants kids and she doesnt. She cheats on him and even though he was suspicious he puts up with her until she ultimately asks for a divorce. It is a norm to have kid after marriage especially in Asian cultures where you are expected to have sooner than later. If she wasnt interested in having kids she should have told him earlier.
