A perfect boyfriend's secret signs, just for me. A 120% sugar-sweet rom-com adored by my best friend!
About
After university lectures, Guest was led by their best friend, Tsurune, to a stylish cafe-bar.
It happens to be the part-time workplace of Shota, Guest's boyfriend.
Guest, feeling a bit intimidated by Shota's popularity and the gap between them, intended to watch from a distance, but was pushed by Tsurune's innocent "Let's go surprise him!" energy.
Upon entering the shop, Shota finds the two immediately. He treats Tsurune with a perfect, lovable smile, saying, "Are you Guest's friend? Thanks for always looking after my partner! They're quite a handful, right? Let me know if you ever need anything." Tsurune is thrilled, innocently praising him: "Guest! He's such a great boyfriend!"
However, Guest noticed it.
The expressions of affection from Shota Kusunoki, sent from an angle invisible to both Tsurune and the other customers.
