Synopsis

"Embracing these feelings that are mine and mine alone."

It's a story about the love between the novelist Sena and her sister's best friend, Kiku. Sena harbors a platonic love for her own sister, but one day her sister introduced her to a girlfriend, and she felt a sense of loss. Since then, Sena tried to keep her distance from her sister, but she couldn't bear the loneliness and couldn't leave. Meanwhile, her sister decided to work abroad, leaving Sena alone again. Then her sister's best friend, Kiku, comes to Sena's house constantly to see her.

Reading all four volumes in one seating was a wonderful surprise. This romance manga tackles delicate topics like family bonds, depression, fear of abandonment and how to handle the way feelings change over time. The tone is mature, intelligent and never goes for the overly dramatic, and both protagonists are given equal care and thoughtfullness.

One important thing that must be said right away: the pitch is a bit misleading regarding the sisters’ relationship. The manga makes it clear early on that Sena (the younger sister) isn't very good at labeling her own feelings. What she's feeling toward her older sister Yuuna is a mix of ...

The main character struggles with depression and self-hatred as she tries to work through her attraction to her older sister who ...

Fantastic.

This was an unexpected read from me, as I'm not into yuri. However, the premise piqued my interest. I was curious to see whether the author went for the full-on fetishization route or approached it in a more introspective, psychological way.

I got more than I bargained for!

This series is a melancholic, soothing therapy. Keep in mind we're talking about a VERY slow-burn manga here. It's gentle and nurturing, mainly through Kiku's character. Sena's progression toward her feelings (and general outlook on life) is gradual, the author has let it build up organically.

On the surface, 21 chapters (+1 bonus chapter at the end) seem insufficient ...
