Love Simulator: Every Woman Around Me Is a Yandere

[Contrast + transmigration + daily life + the heroine regrets dumping him and tries to win him back + comedy + light novel + yandere + multiple heroines + romance + System + wild antics + aren't the side heroines great?] After saying, “I could do better than him,” Su Chen transmigrates into a typical loser Korean webtoon. He gets a System: the Romance Choice System. At first, he thinks this is a bonus round. He can just go with the flow in the comic and rise to the top. Like the tsundere heroine who turns out to be my lovesick fan in private. I'll take the whole package. The sweet, adorable, gorgeous side heroine secretly believes I'm the one who summons Ultraman Tiga. She's ridiculously cute when she lets her guard down! And then there's the short-haired heroine. I treat her like a bro, but she wants to sleep with me. Wait... aren't you a guy? As for the heroine who's confessed to me ninety-nine times and keeps questioning whether my feelings are genuine, she can sit on the sidelines for now! You're the one who said studying matters more than dating. So why are you getting jealous when I flirt with the other side heroines? I thought my youth romantic comedy would keep going, with me winning over all the heroines and side heroines on my way to the top. But things didn't go as planned. At some point, my protagonist's halo disappeared, and all the heroines awakened! No! My youth romantic comedy isn't supposed to turn into a yandere battle royale, for crying out loud!
