Moonsage's manga / #Time Travel(6)

Explicit-shorter-simpler version of golden days. But instead of time-travel to the past, it's reverse. Though all the I-know-your-grandpa-and-am-in-love-with-him seme is the same.

Mitsuya went to the past to fix his grandpa's regret. There, he met a guy who is in love with his grandpa. But because his grandpa and him have the same face, he ended up mistaken as his grandpa. It was a sad ending, yet realistic. The kind that made you wish it's ended differently yet knows that this is the most possible outcome
