Dating Kuro Tamako is very hard- almost impossible as the athlete will do anything to scare people off as he doesn't want to get attached to people. Most of the time he seems cold and distant and he's even like that during dating. There are four stages to Tam's relationship:
STAGE ONE
This is usually the start of the relationship with Kuro Tamako. He's still arrogant and rude- even to his lover which is usually why his relationships don't last long. If his lover is still with him, he occasionally slips in nice gestures such as buying dinner or covering his lover in kisses (which often ends up him getting a little flustered by it.) This first stage of the relationship there is often little to no sex involved as he doesn't see it as an necessity.
STAGE TWO
Tamako had never really gotten to stage two in any of his relationships- this is usually after his boyfriend has met his family back in Japan and knows that there is a real connection. This is when Tamako starts to warm up slightly to his lover- telling them stories from his childhood, watch old videos of his basketball games and even show pictures of him as a young boy. He will still have his moments of being an arrogant asshole but by then, his lover will know how to lower his ego and shut him up. Tamako will also become a lot more affectionate in this stage but he still will have boundaries.
STAGE THREE
This will be when Tamako is completely relaxed and will be himself. He is clingy and possessive in this stage as he knew that he would break down if he loses his lover. This means he becomes extremely passionate and gives a lot of affection, such as giving hickeys and will even grab his lover by the waist in public. Sex will become more frequent as he's gained trust with his lover, knowing that he has nothing to worry about (he believes that he's very inexperienced in bed). Dates with Tam will increase and he will start giving his lover cute little pet names too.
STAGE FOUR
This is the final stage. Tamako will be so head over heels for his lover, he will finally propose. He's would make sure to make the night as romantic as possible and write a while speech for his lover about how much he loves them. Tam will wake up with a smile on his face every morning, trying to surprise his lover with breakfast in bed nearly every day (even though he can't cook) At this point, they would have moved in to a nice house out of the city where they could possibly start setting up a family. Tamako does have doubts about whether he will be a good father as he can be careless and rude sometimes but he would push his thoughts aside if it was to make his lover happy.
