@hugorito420 I agree with box2024's reply. So, I recommend you to read chapter 102 again to see what have been done during and after Shinobu made love with Sakura. What he did with Fumi was good but it could not compare to when he did it with Sakura. Please reread it and you'll see the big difference. Thanks to the illustrator, Keishi Nishikida sensei, for the details in his drawings.
Again, you'll understand why people get angry at Sakura in chapter 129 who threw away everything we've seen for 100+ chapter in exchange of the sex pleasure till the morning (she immediately changed agency and boyfriend). Why we blamed Airi Katsura (sensei) that she forgets what she did in the former 100+ chapters like everything was her lie.
