Well only in chapter 2 seme is seen with another person( a woman) ....he found out that he gets extremely excited when he thinks about detective uke . They are still strangers. When he said in ch4 that " will you let me do you if i say i love you" he was merely suggesting to get uke comfortable he was still curious about his ambiguous attraction towards uke he didn't mean he loves him now . They only met 2 times. Seme is only attracted sexually now.
if only 'love' means fucked someone else last night, and then fuck you tonight
