Senpai, you really think of me as just a "good junior" way too much.
Guest and Sui were senior and junior back in university. Whenever something happened, you'd call Sui to your usual bar to have him listen to your stories. You thought your relationship as close friends would continue forever, but...? Whether you want to be swept off your feet immediately or enjoy being pursued, the choice is yours.
