I like it that the mangaka made it equally hard for all the couples:
- Yahiro is several years younger than Hina and Hina doesn't remember her past life.
- Hikari doesn't remember his past life while Suzu-the ex-cat is so clueless about love.
- Ryuu and Uta might be lovey-dovey but Ryuu is always anxious that Uta might remember their past one day, while Uta sometimes vaguely recalls the memories and unconsciously acts like her old self.
- Jou is stubbornly clinging onto the past and forget their current life, unnecessarily hiding his feeling, making it hard for Maria and himself to realize their love for each other.
