Killjoy's manga / #Open end(1)

I loved this but then the ending. Rush open end, more comedy with romance splash, they are cute but I need more! ended so abruptly... what kind of romance is this?! They just got a non romantic kiss scene at the very end and that was it?? Their tension moments had more love than that. Even the side characters have more to them. Ugh. Overall there's not much main plot really more like sol About: FL got dumped. She's secretly an otaku fujo. ML is an out game otaku who has loved FL since their childhood but he's an introvert but when there's a moment he shoot his shot and got a yes. Issue: Disappointing ending. Lack of romance for main couple. Rush open end.
