If Daisuke canonically couldn& #39;t do the things normal children did, and Sayuri still let him live his childhood as well as he could, she probably wished for him to find a friend, too. So that scene could be Daisuke rushing home to tell his mother about a new friend he& #39;s met+
That evening. But Daisuke can& #39;t be selfish (figuratively speaking) without facing the consequences. He gained a friend, but lost his mother. A never ending cicle of give-and-take Daisuke& #39;s been stuck in for probably his entire life.+
And that could be the reason why Daisuke went abroad and indulged himself: to test the boundaries of his selfishness. How costly would it be to drown his sorrows and whether or not he& #39;ll be able to hog into something without another one slipping out of his grasp+
Which now connects to Haru, a person so far from (indulgent) selfishness that Daisuke couldn& #39;t help but observe him. A clear contrast between the two that drew Daisuke in in a way that he wanted to test the limits of Haru& #39;s selflessness (see literally every episode of FKBU)+
And yet, Haru doesn& #39;t back down. He saves the culprits in episode 1, Mito admits that Haru& #39;s saved him in ep2, he tries to stop the terrorist in episode 3, he helps the little boy in episode 4 and most importantly, he helps Daisuke. The same man who& #39;s been pushing his boundaries+
and testing his perseverance. Haru gave him a place to stay the night, a warm meal, he even gave him (a man with unlimited balance) money to go back home without asking for anything in return. That& #39;s when Daisuke realizes that he& #39;s starting to be selfish for Haru, and that their+
relationship goes beyond co-workers : Haru thinks of him as a friend. But Daisuke knows better than to pursue the thought of them actually being friends, he& #39;s tested the waters before, he knows the rule of give-and-take. So Daisuke gives one last time, then throws it all away+
![Which is why Daisuke refuses to talk things out with Haru unless he falls again and drags the man with him. Even when Haru perseveres, tries to get Daisuke to talk, he keeps it all to himself not because he doesn& #39;t trust Haru, but because he doesn& #39;t want him involved.
