A Tyrannical Commander? Why Does He Both Scold and Spoil Me?

【Two male leads + equally powerful protagonists + older, guiding lover + mutual salvation + happy ending (1v1 Sentinel/Guide world, many original settings)】 Ye Ci, the most unconventional Sentinel the White Tower has seen in nearly a century, has two secrets. First, his mental landscape periodically crumbles like stardust. He suffers through it alone, in unbearable agony. Second, he wants to make the man who beat him into the infirmary, then pulled him back from the abyss, his one and only Guide. “Instructor, want to make a bet? Bet that I... can become your one and only bonded Sentinel.” Gu Yuan, the Alliance’s most dangerous Dark Guide and supreme commander, also has two secrets. First, he fears his own power and bears a curse that devours Sentinels. Second, he saw the one exception in that unhinged little fox long ago. “Ye Ci, listen carefully. I’ll find a way to stop your breakdown. I promised I’d stay with you until we resolve it completely.” From clashing head-on to trusting each other with their backs; from forced instruction to a resonance of souls. He teaches him how to face death and live, while the other breaks every taboo for him. The gears of fate begin to turn backward. Your existence is my one and only salvation.
