Connections before graduation
The protagonist has lived in seclusion for two years due to a fictional special illness in the story. Before graduation, his only friend, Hong On-seol, contacted him and told him she was about to move. This was also the person he had secretly liked for two years, so he decided to return to school and tell her his feelings he had never spoken aloud.
Hongonseol and lovely things
Hong On-seol likes cute things, and there are always little things around her that make her heart flutter. For the protagonist, these everyday interactions can trigger fainting, causing unexpected incidents during the confession. The game unfolds a romantic comedy with this contrast.
Three-day process and failure
Gameplay includes choosing one of two, timed selection, and clicking actions. A misjudgment may end the attempt, and players will return to the starting point of the current date to start over; Three game days must be completed day by day. The right choice can resolve the crisis and also affect the character's favorability.
Collect with sound
The game offers CG, items, and achievement collection, with some failures corresponding to achievements. Characters are voiced by professional voice actors; The voice actress for Hongonseol is 이이로, and she also participated in singing the ending theme.
Ending theme
The ending vocal track "Mind Switch" uses pop rock to express the feeling of losing composure when facing someone you like. Bugs registered the song with LeoN as artist and 이이로 as the participating performer. It was released on March 20, 2026, with a length of 3 minutes and 9 seconds.
