I think they just have their own thoughts and reservations about each other and nothing else
What do you mean sorry?
Like each one of them always have an internal monologue regarding the other’s actions without actually communicating.
Like the swimmer thinks because the mc likes his brother had something physical with him or how the mc allows the swimmer actions because he thinks he’s doing it for some bs reason related to the brother.
Like there’s no communication whatsoever.
At least that’s how I see this,
Wait so does ml think mc and brother already have that kind of relationship he seemed surprised mc never sucked dick before honestly I thought it was quite obvious bro was a mega virgin (which is totally fine no shame)
