very very very loooong story short. mizuki is canonically trans and was terrified of telling ena bc they met online and ena thought she was cis so she kept pulling away and ena kept dragging her back and promised her she'll wait for her to tell her what is bothering her by her side, forever if necessary (ena is impatient and impulsive and waits for no one btw) and mizuki promised to tell her when she's ready but thinks, "i lied to her. i thought she'll be by my side forever, if i never tell her" and then when mizuki got horrifically outed by some classmates ena kept on chasing after her (literally, on her noodle legs, she chased her for 3km and collapsed and couldnt walk anymore and pls keep in mind ena is weak and slow and mizuki is like. rly athletic) and she fought for her tooth and nail so they could be together again and told her nothing, nothing would compare to the pain of losing her and accepted her fully and unconditionally VOTE FOR THE T4C YURI EVER also they always bicker, they're raigebaiter x raigebaited, they love shopping together, are both foodies, they both like make up and fashion, mizuki fixes ena's clothes, it is implied ena painted mizuki for her art school assignment titled "my tranquility" and they're cherry tree colored (pink & brown) bc their love story starts and ends with a cherry tree and they have matching white dresses with matching cherry blossom rings VOTE FOR THEM RN they're the most in love ever 🌸
