Kaguya-sama: Love Is War manga volume 15 features story and art by Aka Akasaka.

Turns out confessing your feelings is the easy part of a romantic relationship... Now Kaguya and Miyuki have to figure out how to behave in a relationship. Kaguya retreats behind the ice shield she built to protect herself years ago. Miyuki believes only an ideal version of himself is worthy of love. Ai/Haski, as usual, is caught in the middle. Will our two not-star-crossed lovers ever learn to let go and just be themselves...?

First, you have to love yourself.
