This work, centered around Hikari-senpai, a popular figure in the university club, delivers a shocking NTR development full of a sense of betrayal that directly hits the brain. I actually watched it, and Hikari-senpai's character is incredibly vivid—usually bright and friendly, but when she switches to seduction mode, her devilish charm explodes. In the early drinking scene, natural chit-chat and realistic proximity induce heart-pounding excitement, followed by intense French kisses and the lewd sounds of fellatio that fuel the feeling of 'I have a girlfriend, but I'm doing this!' The immersion is flawless without any sense of acting, and the passionate interactions, though not between lovers, can be called playful love. I was impressed that the guilt of cheating isn't felt by the viewer but is given by the partner. The natural dialogue and push-pull dynamics are superb, as is the closeness, and I've been captivated by Hikari-san's skillful line delivery since a few works ago. Particularly in scenes where her jealous acting shines, the emotions are palpable, and I have high hopes for her future VR works. Hikari-chan, keep up the great work!
