Romantic ja Mono Tarinai

Kousuke and Shuuji have been dating for three months now, but they haven't even kissed each other yet. All they do is meet up after work and have dinner accompanied by a boring conversation. They also follow the same quiet routine on the weekends. Since Shuuji is sick of this boring relationship, he prepares for their first time together by loosening himself up, and it turns out to be a lot more pleasurable than he expected and he winds up getting hooked on it... This comedic love story full of happiness and lust is about these two lovey-dovey guys who find their relationship challenged when Shuuji's older brother shows up.
