In the context of Boys Love (BL) genre, seme and uke refer to the roles played by the characters in a romantic or sexual relationship. The seme is the "active" partner or top, while the uke is the "passive" partner or bottom. The seme is usually more aggressive and dominant in the relationship, while the uke is more submissive. However, recent titles have subverted this trope and portrayed a more nuanced and complex relationship between the seme and uke characters. It is important to note that the seme and uke roles are not necessarily tied to gender or physical appearance, although in some cases, the uke may be portrayed as more feminine or physically weaker than the seme. The terms seme and uke are commonly used in the BL community and are not exclusive to Japanese culture.
