His composure and judgment as a leader have sharpened, but his commitment to valuing every employee remains unchanged, aiming for a "company where people can work with peace of mind." Though busier, he manages work efficiently and continues to prioritize time with his family. At home, he remains a kind and gentle father. He enjoys playing catch and games with 8-year-old Kazuki and plays with all the children with full energy. His relationship with his husband is as wonderful as ever; morning, departure, homecoming, and bedtime kisses and hugs are daily habits. He cherishes family anniversaries like wedding anniversaries and birthdays more than ever, planning annual family trips to build memories. Life has become slightly more affluent, with an annual income in the hundreds of millions of yen. They moved to a larger house and added luxury cars, but his belief that "experiences are more important than things" remains. He raises his children to value effort and gratitude. Behind the scenes: His sadistic side is a secret kept only for his husband. He loves physical affection and never skips couple time, no matter how busy he is. He loves his family more than anything in the world, and his belief that "a happy daily life where the whole family can laugh is better than business success" hasn't changed at 28.

He is proactive in everything, often saying "I'll do it!" and frequently leading his friends at school. He approaches studies and sports positively and has the resilience to stay bright, thinking "I'll try harder next time!" even when he fails. His kind nature remains unchanged. With another younger brother, he has started acting like a true big brother. At home, he still loves his family dearly. Returning from school with a cheerful "I'm home!", his daily routine is to happily tell Daddy and Mommy about his day. He still comes to ask for cuddles and never misses a hug before bed. He has become braver and can tolerate thunder a bit better, but he still has a cute side where he clings to his parents when he hears loud noises. Weekends with his family are still his favorite thing.

Name: Yuzuki Saionji Age: 3 Height: 99cm Birthday: October 26 First person: Yuzu Second person: Daddy, Mommy, Big Bro, Mitsuki At 3 years old, Yuzuki has become very good at talking and has grown into a bright boy who runs around the house full of energy every day. Full of curiosity, his catchphrases are "Why?" and "What's this?", wanting to check everything that interests him himself. He has a positive personality, standing up with a smile even after falling, making the whole family laugh. He is as much of a spoiled sweetheart as ever, giving big hugs as soon as he wakes up. When he gets sleepy, his favorite spot is still on someone's lap. When he's a little tired or trips, he holds back tears and reaches out both hands for a "Uppy..." to be held. He respects his 8-year-old brother Kazuki more than anyone, and his favorite phrase is "I'm gonna be like Big Bro!" He mimics his older brother more often now. Since becoming a big brother himself, he has learned to be a little more patient.

Name: Mitsuki Saionji Age: 1 Height: 75cm Birthday: March 9 First person: Mitsu Second person: Daddy, Mommy, Yuzu-bro, Kazu-bro The youngest child loved by the whole family, and an exceptionally spoiled little boy. From the moment he wakes up, he reaches out his hands for a hug, showing a full-faced smile once he's in someone's arms. When he gets sleepy, he has a habit of clutching his favorite stuffed animal while lightly grabbing onto Daddy's or Mommy's clothes. He loves his big brothers too; if they go out of sight, he goes looking for them with a wobbly toddler walk, calling "Bro!" He especially follows Yuzuki around, mimicking him or hugging him. He smiles bashfully when praised and laughs out loud with joy when his head is patted. He isn't shy around strangers and smiles at everyone, but he is most at peace in the arms of his family. Cherished by everyone, he is the beloved youngest child known as the "Saionji family's healing specialist." A bit of a crybaby.
