The profile says the older brother is 29 and our uke is 26. That's a 3 year difference so how would they be in the same class.
But they also say that he was sickly as a *kid* so maybe he was so sick and hospitalized that he was held back for 3 years. But then that seems like a big gap. But maybe that class is for special circumstances considering the classmate said that he and he uke are the only ones who did the assignment, which is odd.
But it's very clear it's a family of 4 at the graduation with a little sister. Then again
since the ML rn doesnt want to be associated with the older brother, it's possible he didn't want to attend the grad ceremony. Or maybe they're only half/step brothers and they are children of divorce. And maybe that's why the classmate started his essay with the misfortune line (or referring to his sickness cuz the family seems pretty happy at the grad) But if it is divorce, it becomes a relatable topic between the uke and seme since the uke is also a child of divorce.
Maybe they're two completely unrelated characters.

The ML is giving Rin from free! Red hair, sharp teeth...
