Can The mods add this info to Episode 270? I think it's relevant to the overall story of the show
In Episode 270 (4:09), Haibara acknowledges that she is attracted to Shinchi kudo (Conan) by internally saying to herself "Without considering the consequence, you pursue truth and justice. The burdens you bear are yours alone because you feel obligated to protect those around you. Your dangerous boy-like personality in so painfully and achingly intriguing. I wonder if you realize that that pure scent of yours is strangling me, her (Ran), and yourself with loneliness, uncertainty, and vulnerability"
In return, as she always teases Conan about his feelings to Ran and how he accepted her chocolate on valentine's day (end credits scene of episode 269). He says with a sad expression (8:30) " I'm not happy at all since after so long, I haven't told her anything...If I told her how I feel, she'd just miss me even more. After all, I'm the guy who's been breaking her heart by making her wait an eternity even though I'm always by her side. I don't want to see her cry any more, even if it means I no longer have a place in her heart" To which Haibara says to herself: "pitiful, Both of us"
