2-banme ni Suki na Hito.

Ema has been dating her childhood friend, Aoi, for 8 years. They have been living together for four years, and Ema hoped to get married one day... However, Aoi has been neglecting the housework recently, and even treats her birthdays as an after-thought. Ema's desire to be with Aoi as a lover sometimes feels one-sided. Just as Ema starts to worry if they can even get married at this point, she runs into her high school crush, and he's just as kind as he was back then... (Source: Manga Plaza)
