Relaxation + workplace + strength + tsundere and abstinence are attacked by x hot bastards
They dislike each other, but encounter a level 10 "fate storm";
They don't want to meet each other, but are forced to become close friends living together;
They avoid cooperation, but they can always achieve the work effect of 1+1>11 unintentionally;
They are both straight men, but they accidentally went to the wrong bed and fell in love with each other.
A romance between a calm and ascetic project engineer and a passionate sales engineer who slapped tables, fought with each other, and had sex.
The fate is beyond words.
