I swear his friends unlike his family are the only reason he still goes outside.
On the other hand good to know that the gigachad gave the MC the push he needed and asked Toujou for her contact, the only thing that baffles me is how in the hell his brother is not aware of all the crap MC was enduring, I mean he "adore" his lil bro so it makes no sense he isn't aware, but oh well, you can't have a romcom without stupid drama product of unresolved stuff that shoyld had been adressed earlier on it
you should go back and read the chapters involving the sports festival.
Tohno gets along great with his family, both parents and brother. He sees his brother as a rival of sorts, but also looks up to him; and his parents have never shown any indication that they play favorites between their children, and supported Tohno throughout his childhood.
The
only people we see directly contributing to the MC's core character problem, are the
other people around them who put Rei on a pedestal and ignore Tohno. His parents don't do that. His brother doesn't do that. His friends are clearly there on his side, as you said.
And I don't believe it's been expressly stated, but I would suspect that Rei isn't aware of Tohno's problems of being compared to him constantly, because Tohno himself is clearly not the kind of person to open up to others.
We see that in this very chapter. He's fortunate that his friends care about him and are pretty insightful, because that's how they know something's up with him because he just .... doesn't talk about himself or his feelings. Houjou also clearly picks up on his moods and is paying attention to him, also shown in this chapter - she just doesn't know his story, so only sees his face, and doesn't understand the context.
So Tohno likely just keeps it all to himself as "his burden to bear" and doesn't involve his brother because he's just bad at communicating and expressing himself and would never be the one to initiate that sort of conversation.
That's obviously a flaw - communication is important for any healthy relationship, but it
also very clearly represents a narrative element of growth for Tohno, wherein he finally does speak out and state his mind - to his parents, to Rei, to his friends, and of course to Houjou.
And I imagine that facet of his character will directly relate to how his relationship with Houjou progresses and changes, and will become instrumental in actually coming to realize that she cares about him and he about her, and that where she's concernerd, it's not actually about his older brother.
