Actually the Jun x Tatsuya element of the game is a little more than subtle hints. In the game you have conversation system with demons and it's possible to team up with members. If you actually tell Jun you love him, then you get a team up conversation ability between the two which is Jun flirting with Tatsuya. Likewise, if you tell Maya or Lisa, they partake of the system. It's not full on modern RPG snog fest but for something that came out in the 90s, it was pretty bold.
