can anyone help me find this manga? i forgot its name...

so, it is a yaoi. where the mc is royalty like youngest son of the king or third son something like that, he is blonde and has long hair (maybe) he was in love with his guard in his past life and was killed, so in this life he tries everything to make him notice him. there was a scene where they where at some kind of party and he was drugged and kidnaped and was about to get assulated but the guard saves him. and the last chapter i read of it went something like the guard and him having sex? where he says "i'm sorry, i forgot u like being simulated boths sides" and starts fingering him?. there was also this chapter where his older brother comes and he also fucks mc? while the guard gets jealous? pls help me find it, if you know this manga! (it was a coloured one if that helps?)
