In both: the male leads fall in love with the female leads first, at a young age. The two couples have an age difference, female leads being older. The male leads remained in love even when female leads were in another relationship (unrequited love). The female leads focus on their career and male leads support them. The professional nicknames of male leads (DT in Go Go Squid 2 and Heisha in Sweet Games) were inspired by the female leads without female leads knowing. The families in both stories support the protagonist couples. Friendships and teams come together equally with the goal of bringing victory to the team (in Go Go Squid 2) and the company (Sweet Games).
