I Love You, Monster: The Blindfolded Wife x The Masked Husband Chapter 98 Sei number two?

The couple were finishing breakfast when Davi talked.
"Uhm… my brother actually wanted to meet you. Can we go visit him today? Of course if it's okay for you to become Sei-ér today…" As soon as those words came out of her mouth, Davi paused as she bit her lip.
Shoot! It actually slipped out of my mouth.
"Sei-ér?" Sei repeated the name she just mentioned, causing Davi to scratch her neck lightly.
"Err… it's… it's the name I gave to the you in disguise," she said hesitantly as she waits for his reaction. However, as if a crow just flew noisily above them, no word came out of Sei's mouth. That moment, Mr. Chen who was just passing by suddenly laughed, causing the two of them to turned their heads towards him.
As soon Mr. Chen noticed their gazes, he cleared his throat and he smiled. "Don't mind me, don't mind me," he said and he hastily walked away while he was giggling in his mind.
Sei-ér? Sei number two? Pfft! Nice name little Miss, nice name.
Shortly after Sei agreed to visit Davi's little brother, Zaki then accompanied Sei into his study room to help him put the mask.
"Sei-ér huh… pfft! How are you liking the name she gave?" Zaki asked mischievously.
"Just focus on what you're doing."
"Haha. Don't worry, this expert will see to it that Sei-ér's face will be perfect."
"Shut up."
"What. You don't like the name? Should I tell her you dislike it?"
"…"
"Pfft! Looks like you can't do anything about it. Haha."
…
Davi and Sei-ér were approaching Haru's apartment when they bumped into caretaker Sue, the woman that Mr. Chen hired to take good care of Haru since he was discharged at the hospital. Although when Haru recovered, she was just now working as his part time caretaker, as requested by Haru himself even though Davi wanted the caretaker to live with him.
"Good day Mrs. Sue," she said as she approached her. The cheerful caretaker then told her that her brother was with his friend inside so Davi and Sei-ér then walked towards the door.
And as soon as it opened, Davi immediately hugged his lovely little brother. However, that moment, Haru's eyes were glued into the man behind her.
"Sis, is he your husband?" he asked and Davi instantly nodded as she let go of him.
"Mm. It's him, my husband," she said as when Haru stepped closer towards him. Haru looked up the tall man with amazement. Apart from his handsome and manly look, Haru could somehow tell that he was no ordinary man.
"I'm Haru. Nice to meet you." he said and the man just landed his big hand into his head as he nodded at him.
"Call me big bro," Sei-ér said and the boy's eyes immediately sparkled.
"Mm. Big bro, thank you for always taking good care of my sister," he answered with an earnest voice. That moment, Sei could tell that the boy really cares about his sister more than anything. So he landed his big hand in his head again as though telling him that he is doing a good job as his wife's little brother.
