Shigoto de Tsukareta Shachiku no Ore ni Bishoujo ga Karande Kuru no daga……

I, Nagayama Makoto a 27 year old working at a trading firm, am bidding farewell to my life as a nihilistic corporate slave. One day, tired from work, i muttered the words "I want to die" when suddenly a JK death godess called Hina appeared and told me in response to my wish i now only have one more year left to live. I somehow manage to solve her misunderstanding, but as it turns out the only way for me to revert the death sentence is if i fall in love with someone and marry them!? I, as someone in a relationship with their job start to despair, seeing that, Hina made a strange suggestion. 「I will teach you how love works!」 And with that my life together with Hina starts. She encourages me for work, shows me around several date spots, and teaches me how it feels to be loved. I feel like Hina's advances are a bit agressive but this much is to be expected if she wants to teach me about love.... right?
