Ten Steps Will Cost Your Life! the Tsundere Witch Smells so Good

[Single heroine + two-way running + tsundere witch + relaxed and funny + mutual favor] Vespera once swore that even if she married the most disgusting slime, she would never look at that dull and rude shield guard Leo again! But a ridiculous hangover made them bind the most unsolvable symbiosis contract in ancient times - the "Concentric Lock". Within ten steps, they were roommates who disliked each other; Ten steps away is the absolute punishment of soul tearing! The most terrible thing is that this contract not only limits the distance, but also shares the heartbeat and physiological state! "Death Shield Guard, stay away from me..." As soon as Vespera finished speaking, the dark gold chain on her right wrist tightened suddenly. With the crazy synchronization of her heartbeat, the cold red-haired witch's legs instantly became weak, and she collapsed directly into Leo's arms, her face flushed. When the bathroom door was accidentally opened, she panicked in the thick steam, but the contract chain on her wrist erupted with a golden-red light that represented extreme throbbing and shame, pushing their heartbeats to the edge of losing control! The late autumn rainstorm hit, and in order to resist the biting cold and fever that came back from the contract, she had to put on his loose white men's shirt, blushed and got into the same double winter quilt, interlocking with his fingers, using their body temperature to save each other... The tough-talking genius witch finally fell into the warmth of the rough shield guard's fingertips. When Tsundere's defense completely collapses, will this chain of fate that binds them together become an irreversible curse, or will it be a lifelong bond that the two cannot let go?
