It's so realistic, i love it. Finally real unrequited love. It's so boring to see those "happy endings" all the time. I'm so glad that Uta has made a step forward to get out of it. I hope they won't end up as happy family living together like nothing happened...The only way for Uta to escape those toxic feelings is to stop seeing Kaoru.
The fact that Kuro is changing inside also makes me so satisfied. I'm looking forward to see her realizing that their relationship can't stay in the same place forever.
