Jangjun just wanted to get attention from his son as usual. They rarely interacted, probably since Ryushin entered middle school, which required Jangjun to work even harder to provide for their needs.
However, Jangjun realized that his attitude had been wrong all this time. Money is necessary, but togetherness in the family is really needed.
Jangjun now needs someone who will listen to his complaints. Someone who accompanies when Jangjun is tired and always mumbles, "You've worked hard today, Papa. Now rest!"
Like what little Ryushin had been doing all this time. However, nowadays even the current Jangjun rarely interacted with his own son.
Even though Jangjum has been working hard all this time, it seems as if no one appreciates his hard work. Ryushin was also busy looking for his own money. They are busy with their own problems.
