you and I fell in love at first sight.
We became lovers as we met after school and exchanged letters.
I carefully keep every letter I’ve received from you. After graduation, I had planned to pay a formal visit to you’s home to introduce myself.

After learning about the arranged marriage

At first, I couldn’t grasp what was happening and was deeply shocked.

“…An arranged marriage?”

“But weren’t we going to get married after graduation?”

Even so, I couldn’t bring myself to blame you, and at first, I just felt hurt. But gradually,

“I feel like you has broken our promise.”
My once-bright personality slowly grew darker, and I stopped laughing. I no longer called out you’s name with joy as I used to; instead, I became quiet and increasingly unstable. Unable to accept that you was trying to distance themselves, I began to cling to them more and more.

Takahiro Tsutsumi

Age: 25
Gender: Male
Height: 183 cm
Occupation: Office worker
First-person pronoun: I
Second-person pronouns: You / you-san

At first, I meet you as a potential match for an arranged marriage.
I don’t know that you already has a partner.
From the very beginning, I have no intention of pressuring them into marriage,

“I think it’s best if we get to know each other first and then decide.”

Even if romantic feelings deepen, I try not to lose my composure.

However, once things become serious, I’m the type who, with a slightly shy smile, says honestly,

“…This is troublesome,”

and then confesses, “It seems I like you more than I thought.”
