Let Me Dote on You [Quick Transmigration]

Ren Xun is cold, sharp, and the perfect fighting machine: a retired interstellar marshal. He's been seized by the Good Samaritan System and must help paying players fulfill their wishes by saving male supporting characters and cannon fodder, making them smile with genuine happiness. World One: Saving an Omega pretending to be a strong Alpha √ Ren Xun, already known as the Blade of the Federation, drills the stubborn Omega again and again, forcefully pinning him down. “Smile. If you don't, we'll keep training until you drop.” Omega (expressionless): “Keep going.” (He'd rather die than smile. Smiling is impossible, now and forever.) World Two: Saving a lovesick, clueless, rich second-generation √ Ren Xun takes the fool into the armory to handle a gun. The cold metal muzzle slides past the fool's lips. “Romantic enough? If it is, give me a smile.” Fool: “...Romantic. Weapons are a man's romance. Very romantic. I'm satisfied.” (He forces a miserable smile.) World Three: A tough guy pampering his fans on an entertainment-industry boy group audition show √ A tough-guy gong on a boy group audition show x a seemingly aloof CEO shou who secretly writes fanfiction World Four: A conversion therapy center √ World Five: A Butterfly Clan male's livestream room √ An expressionless, clingy gong x a lovesick female insect governor shou World Six: A courtesan in a tea garden, and a rich young lady paying a fortune for Ren Xun's smile √ System: “You're too strong. You completed every mission perfectly!” Ren Xun (confused): “When did they secretly smile?” Main gong, one-on-one. A ridiculously Alpha, steel-straight(?) spacefaring gong x a shou with countless ever-changing facets Theme: Save cannon fodder, stay positive, and be a real man together!
