1- He was conflicted. Ren already loved him in a romantic way. But at this point Haru only wanted to keep him close. He found Ren super important (if not he would not have chased him as far as Canada) but he was not sure he wanted "more". He was still conflicted when they came back to Japan. A part of him wanted Ren to call him "Brother"' but another not because it meant that their relationship would not go further than that.

2- Same thing. By that point he knew that Ren was super important to him. I mean when he was drunk the thing he wanted to do was sleep with Ren after all. But he was not sure just how much he actually loved and wanted him. Was he just confusing his "brotherly" feelings for something more? Did he not act this way just to please Ren and bound him to him because he wanted Ren to stay to realize his dream or living with all his brothers in the same house? It's only later in the story that he finally decided to be serious about their relationship and admit that Ren was the one he wanted. For the reason he tought about calling his ex-girlfriend, he was drunk and remembering his first love I suppose. She made an impression on him. Maybe he just wanted to catch up. Maybe he unconsciously was missing her and old feelings surfaced. But Ren telling him to not old back for his sake woke him up. He was more afraid of Ren leaving him than he wanted to catch up with her. And once sober he realized that he was over her, and that she probably was too or she would not have tried to contact him.

Sorry, it was longer than planned.

for your question #2, im pretty sure the seme had already loved the uke he even said in the anime that he wasn't actually going to call her.

Oh, do you know what episode is it? I want to see it

So this mean at the beginning, seme just thinks uke like a little brother and wants to take care of him with intimate actions in the unconscious like kissing, hugging,... but seme doesn't realize these are expressions of lovers for each other. And until uke discontinuity when he's about to call his old girlfriend, he just realized it was love and he loved uke, right?

Oh my god, the reply is disappear. Someone please help me

Well, do you remember what the episode or chapter is it?

I think he lied and was actually conflicted about calling her or not because he kept the card with him while drinking kept looking at it. But it's only my hypothesis.

It's just my idea however? I could be wrong.

I don't remember the chapter but for the ex-girlfriend scene it was the episode 6 of the season 1 of the anime if I recall.
For the moment Haru realized his feelings, I don't think it was right after this part but even later in the story. Not sure when exactly however. Maybe after Haruko left? Or when he returned to his 25 years old self in the amnesia arc?

Today i have read it and in vol 5 seem like seme doesn't realize his love for uke. He just kiss and act as a lover with uke. Uke likes him but seme likes uke in different way

And thank you very much for heping me
Have a nice day!

The 'charms' ( charms = like pheromones) of the two skater dudes were super strong for our bb whose newly a vampire. When they get home he's all hot for the D which the soon-to-be pair guy notices. Our lil' bb is scared because he doesn't know much of what's going on, so the soon-to-be pair guy uses his charm to calm our bb which also excites him. He says "just listen to my voice" which I think is his 'charm'. hope this helps

sorry wrong page lmao
I think the lil bb had tried some kinky stuff before meeting the other vampire.....

You mean sex? Sorry because i am not good at english so i don't understand this scene well

Oh and in chap 1 uke was in bar and had sex?

I'm not sure what he was doing at that place but they hint that's where he was trying some stuff
