The game's story is a cornerstone of its appeal. You play as , a young man who returns home from his first semester at college. His life has been shaped by a painful past: his mother left him with his uncle's family when he was 12 years old, without any explanation, and he has not heard from her since. Now back in a familiar yet changed environment, he must reconnect with his relatives—his uncle, aunt, and their daughters—and navigate the complexities of his new life as an adult. This emotional core, hinted at by the game's title, suggests that many of the "heart problems" Iker faces are not just romantic but deeply personal and familial.
