"Hu… hu… husband!?" Tianxin was startled, blurting it out instinctively.
"Mm, good girl." Chen Yiran smiled faintly, reaching out to pinch her rounded cheek. "Why are you stuttering now?"
"Uh… just… not quite used to it yet…" A faint blush instantly crept onto Tianxin's fair cheeks. "After calling you 'brother' for so many years, after all…"
"It's fine. From now on, you'll have decades to slowly get used to it." Chen Yiran tilted his head, placed a soft kiss on Tianxin's cheek, and then said with a smile, "Let's go home."
"Mm." Tianxin helped Chen Yiran into his car and then slipped into the driver's seat herself.
On the way home, Chen Yiran leaned against the car seat with his eyes slightly closed, not saying a word.
