The Director Who Buys Me Dinner and Old Fashioned Cupcake for me are like two sides of a coin. The are similar in that it’s a workplace setting, superior/subordinate relationship that is at first resisted or ignored by one side. Old Fashioned Cupcake is more light and fluffy where The Director Who Buys Me Dinner is heavier with more depth and a past with it.

Both of these are BL (gay romances).

The Director Who Buys Me Dinner is a South Korean production.

Beside You and Caged Again are both BL Dramas that involve animal shifters. Both are also Thailand based productions.

Bake Me Please and Bite Me are both Thai BL Dramas with an overall similar vibe to them. They both focus on an established famous chef and an aspiring one. Bite Me focuses on main and side dishes whereas Bake Me Please is desserts.

Both are Thai BL Drama Series that have a gangster vibe to them. In The Heart Killers, it is about a pair of hitmen brothers and a police spy and his mechanic friend. In Jack & Joker, it is about an ex-convict / thief and an enforcer for the mafia.

Both The Heart Killers and Long Time No See are centered around a hitman based storyline that also includes BL or Gay Romance.
