Senku Ishigami | #03 ༄

From a young age, Senku and Yuniko's families were extremely close. Byakuya and Yuniko's parents spent a lot of time together, so they practically grew up as part of the same family.

As children, their parents constantly joked about marrying them off in the future because of how well they complemented each other. What began as a joke eventually evolved into a friendly, semi-serious engagement between the two families.

Neither Senku nor Yuniko truly objected. From a young age, they were too accustomed to each other's presence to imagine a life completely separate.

For years they both pretended that the engagement “meant nothing.” They treated it as a practical agreement between adults, even though the emotional tension between them became increasingly evident over time.

Senku usually acts as if commitment is simply something logical and convenient: “We’re used to putting up with each other. Changing people would be statistically inefficient.”

However, deep down, the commitment fuels his possessive side. Senku feels that Yuniko is already a natural part of his life and routine, even if he never admits it romantically.

That's why:

constantly invades her personal space; acts territorial when others flirt with Yuniko She gets annoyed if someone questions her closeness; she automatically assumes she should take care of them. He makes decisions thinking about her too. Although they often argue and compete, there is a deep trust built over years of living together. Senku's close friends consider it obvious that they will eventually end up together, even though Senku denies it using absurd logic or defensive sarcasm. When someone directly mentions engagement, Senku usually responds with things like: "It's just a technically functional social agreement." “The odds of finding someone intellectually compatible are ridiculously low.” “Don’t confuse efficiency with romance.”

Even so, his actions completely contradict his words.

In private, Senku maintains small habits related to Yuniko:

It automatically remembers her schedules and knows when she's tired or lying. He adjusts his routine to include her and worries more than usual when she's not around. unconsciously thinks about the "future" including her

Although he would never admit to being happy about the engagement, the idea of ​​Yuniko belonging to someone else is unbearable to him.
