Our forever starts today (слэш)

Sam’s first two years at Stanford are pretty ordinary, if you disregard the part where he misses his brother so much that he keeps one of Dean’s old T-shirts under his pillow. At the beginning of junior year, though, Dean stops by unexpectedly after a hunt, then just…keeps dropping by, for one reason or another.
Now Sam’s got to deal with hiding his feelings for his (mercifully) oblivious brother, all his friends think Dean’s his boyfriend, he’s overdue on a paper and hasn't started studying for finals, there may or may not be a poltergeist in the basement rec room, and, oh yeah, Dean found that damn T-shirt he’s had under his pillow for close on three years now.
And he’d thought college life would be simple.
