After being transported to this world, Nara Kazuki discovered that as long as he grinded enough proficiency, his jutsu could level up.And so, he began walking a very... peculiar ninja path.

Qin Mian opened his eyes and found himself lying in a leaky thatched room. The problem was that he was still in his family’s villa beforehand! What’s more, there was another man lying next to his leg in the quilt!

“You, you, who are you?”

The man sat up quietly, his upper body exposed as looked at Qin Mian for a moment before he carried a worn out bowl with a cracked corner from the low table at the head of the bed. The man said in a muffled voice, “Wife, drink water.”

Qin Mian’s eyes rolled backwards and he passed out.

TN:
Title explanation: 勉为其男 [miǎn wéi qí nán] have the same sound as 勉为其难 [miǎn wéi qí nán] which means to do something reluctantly. 勉 [miǎn] is also part of MC’s name: Qin Mian.  Also, 其[qí ] sounds the same as 妻 [qi] means wife. So, there are words plays. Basically, Qin Mian reluctantly becomes someone’s man [wife] after he transmigrated.
