This AMAZING! This was beautiful I cried

I really like this! Keith and Lance are in-character and the scene plays out realistically. Many writers would have Keith pour his heart out and Lance comfort him through all of that, but instead you made the wise decision of having them take a small step with the hope of more intimate conversations in the future. And I like that you had them kind of broach the topic of their sexuality without it turning the whole situation weird in terms of their chemistry. This feels just right for where they are in their relationship, making it satisfactory regardless of whether the reader ships them romantically.

Some notes on mechanics:
~ Many sentences start with a lowercase letter.
~ "it was obvious" and "it was evident" in the same sentence is a bit redundant.
~ I think "infliction" is supposed to be "inflection," if you're talking about speech instead of inflicting pain.
~ "if you're not busy" makes it sound like "I could talk to you" means here and now. Maybe clarify sooner that Keith is talking about the future, not the present?
~ "been run into" and "been bumped into" is passive voice. Active voice usually sounds better.
~ I'm not sure about the sentence "as examples ... went". Are there some words missing? What do you mean by "examples"?
