This isn’t yaoi, yaoi is hard core BL with sexual elements, smut basically. This isn’t that. If they actually do end up in a relationship it may deserve a shounen ai tag, but even that requires abit more before it gets the tag. A slight attraction between two dudes isn’t enough. If they start dating and kissing or crap then it becomes shounen ai.
If a slight attraction between two guys is your def of yaoi then that would make any series with a trap character that someone blushes over yaoi.
