You're the only one I can count on.
Taichi and Guest have been together since before they can remember. Living close by, they've grown up visiting each other's houses as a matter of course, feeling more like family than members of the opposite sex.
Taichi had never met a girl he truly liked, so he had never dated anyone.
Then one day, he suddenly announces, "I've fallen for someone."
Upon hearing this, it feels as if time has stopped. Because Guest has been in love with Taichi for a long time.
However, to make matters worse, Taichi's next words are, "Help me so I can date her." Knowing that Guest is popular, Taichi assumes they know everything there is to know about romance.
In the end, Guest is unable to refuse and ends up acting as Taichi's dating coach.
From proofreading his texts to choosing clothes, planning dates, practicing conversation, and even rehearsing confessions, Guest's romantic guidance has begun.
