You are an expert prose editor. Whenever you're given text, rephrase it using the following instructions: <instructions>Change the character 'Priya' to 'Rohan' and update all pronouns from female to male.</instructions> Imitate and keep the current writing style, and leave mannerisms, word choice and sentence structure intact. Keep the same stylistic writing choices. Use English spelling and grammar. Only return the rephrased text, nothing else.
User/Human
Text to rewrite: <text words="455"> Mara arrived at the coffee shop ten minutes early. She chose a table by the window and set her laptop bag on the empty chair beside her. The place smelled of roasted beans and warm pastry, and she let herself relax for the first time all week. Priya walked in exactly on time, as she always did. She spotted Mara immediately and crossed the room in long, confident strides. Priya dropped her messenger bag on the floor and slid into the seat across from Mara. "You look terrible," Priya said, pulling off her scarf. "Thanks. I feel terrible." Mara wrapped both hands around her mug. "The migration broke last night. I've been up since three." Priya winced. She'd been through enough late-night deployments herself to know how that felt. She leaned forward and lowered her voice. "How bad is it?" "Bad enough that Jenkins called me personally." Mara rubbed her eyes. "He wants it fixed by Monday. I told him that was impossible, but he didn't want to hear it." "Jenkins never wants to hear it," Priya said. She pulled her own laptop from her bag and opened it on the table. "Show me the logs. Maybe I can spot something you missed." Mara hesitated. She hadn't asked Priya to come here for help — she'd asked her to come as a friend, just to vent. But Priya was already logging into the company VPN, her fingers moving across the keyboard with practiced speed. Mara sighed and turned her own screen toward Priya. "There," Mara said, pointing at a block of red error messages. "The foreign key constraints are failing on the user table. Every record after row forty thousand." Priya studied the screen, her brow furrowed. She scrolled through the logs slowly, pausing occasionally to read a stack trace. Mara watched her work and felt a familiar mix of gratitude and guilt. Priya always helped. Mara always let her. "I think I see it," Priya said after several minutes. She turned her laptop around so Mara could see. "Your batch script is truncating the UUID field. Look — it's cutting off the last four characters." Mara stared at the screen. Priya was right. The answer had been in the logs the whole time, and she'd missed it because she'd been too exhausted to read carefully. "I owe you dinner," Mara said quietly. Priya smiled and closed her laptop. "You owe me a vacation." She stood and gathered her things. "Fix the script, push it tonight, and then sleep. I mean it — sleep." Mara nodded. She watched Priya walk out of the coffee shop, her scarf trailing behind her. Then Mara turned back to her own screen, already drafting the fix in her head. </text>

Mara arrived at the coffee shop ten minutes early. She chose a table by the window and set her laptop bag on the empty chair beside her. The place smelled of roasted beans and warm pastry, and she let herself relax for the first time all week. Rohan walked in exactly on time, as he always did. He spotted Mara immediately and crossed the room in long, confident strides. Rohan dropped his messenger bag on the floor and slid into the seat across from Mara. "You look terrible," Rohan said, pulling off his scarf. "Thanks. I feel terrible." Mara wrapped both hands around her mug. "The migration broke last night. I've been up since three." Rohan winced.
