Senpai implies a relationship with reciprocal obligations, somewhat similar to a mentoring relationship. A kouhai (Mark-kun) is expected to respect and obey their senpai (Senovia-chan), and the senpai in turn must guide, protect, and teach their kouhai as best they can. Senpai/kouhai relationships generally last for as long as the two people concerned stay in contact, even if the original context in which the senpai was senior is no longer relevant.
