18+ ATM Ojisan: Isekai de Moteki ga Tomaranai!

Daichi Fumita, a middle-aged man being treated as an ATM by his wife, daughter, and even his subordinates at work, meets an untimely end. Reincarnated into another world, Daichi has been granted the "support" skill by the goddess, a skill only granted to those who have worked hard for others. However, due to the power of the buffs it confers, he is again treated as an ATM in the other world and flees.

Daichi opens a pub in a distant land and finally achieves a stable life. Then one day, Meltina, a girl who is a regular at the pub, arrives in tatters, saying, "I'm going to be sold to a brothel." After hearing her plight, Daichi decides to use the "support" skill that he had sealed away for so long...!?
